Quick Extender Pro reviews

If you feel a sense of disappointment or dissatisfaction about the size of your penis, you're far from alone. You're the rule rather than the exception. Concerns about sexual inadequacy haunt men, and penis size is a cause of anxiety. Meanwhile, adult men of all ages who have a larger-than-average penis tend to have a more positive self-image.

In reality, the vast majority of surveyed women in heterosexual relationships — nearly 90% — reported satisfaction with their partner’s penis size. Perhaps the pertinent statistic is that this same survey found that only 55% of men were satisfied with their own penis size. That’s despite the fact that more than 90% of men have a penis length that falls roughly within an inch of average when erect (5.16 inches).

But for men with below-average penis size or men whose partners admit to some lack of sexual gratification from intercourse, you may wonder what your real options are for enlarging your penis. The difference of one inch can seem more like a mile.

Many products and procedures promise to make your penis larger. But which ones are legitimate, and which ones are ripoffs or, worse still, dangerous? One company, Quick Extender Pro, has been in the penis enlargement business for years, so we decided to put it to the test and examine the scientific merit behind its products. Does Quick Extender Pro work to make your penis bigger? Our reviews here will walk you through the pros, cons, and all details so you can decide whether to try it.

Our Findings

Editor's Rating4.25

As long as you use it as directed and pay attention to the signals your body is sending, Quick Extender Pro can be an effective means for adding length to your penis. Real-world gains don’t equate to promises made by Quick Extender Pro and its competitors, at least according to the research, though anecdotal reports of significant growth do exist. The main downside is that you have to wear the device for extended periods to see results. The 6-month money-back guarantee ensures you'll either see results or recoup your investment.

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service or product. For Quick Extender Pro and similar products, we typically concentrate on effectiveness, cost, convenience, and privacy, customer support. Effectiveness gets the most weight in our rankings, with cost and the other criteria having slightly less impact.


Rating: 9 / 10

When used properly, Quick Extender Pro’s devices can help men achieve larger penises, and the growth is permanent. While this requires a time commitment — at least a couple of hours on most days, for potentially several months — Quick Extender Pro works. That said, you might not see the kinds of gains you expect if you buy into these companies' marketing language. Most suggest you’ll experience gains of at least an inch, whereas we’ve seen average gains just below an inch in clinical research. Still, most men would gladly accept nearly an inch in added length.

One potential measure of a given penis extender's efficacy is its maximum tension, measured in grams of force. This tension results from a combination of extension bars used by the consumer and the strength of the springs the company employs in its devices. In our research, only the Phallosan Forte offers more tensile strength at its most aggressive setting, but it’s a larger, costlier device that isn’t as easy to use.


Rating: 9.2 / 10

Generally speaking, penis extenders aren’t inexpensive, but their prices often surprise men who would likely pay a lot more than an extender’s cost to grow their penis. For extenders in its class, Quick Extender Pro offers an exceptionally low price. Here’s a quick look at how the costs of its models compare to other players in the field:

CostRod or vacuum system
Quick Extender Pro Value Edition$120Rod
Quick Extender Pro Deluxe Limited Edition$350Rod
Phallosan Forte$379Both
PeniMaster Pro Complete Set$350Both
SizeGenetics Value Edition$199Rod

As you can see, Quick Extender Pro’s Value Edition is less expensive than the best-priced offerings of many competitors, and its Deluxe Limited Edition is around the same price as some other companies’ base models. There are some less expensive models from other brands out there, but our testing has revealed inferior materials and maximum tension strength below what Quick Extender Pro offers.

Rating: 7.5 / 10

Our convenience rating for Quick Extender Pro is more a reflection of the inconvenience of using any penis extender. As with any other extension device, you have to wear the Quick Extender Pro daily for several hours each day, and you’ll do that for months to see results. (Also worth noting, though: the results are permanent.) But when we compare the Quick Extender Pro to its competitors, we find that it's as easy to use as the rest, if not easier than them. And the materials that come in its packages, like foam tubing sheaths and extra gauze, make the process more comfortable.

For an initial customer experience, we found the process of purchasing and receiving the device to be straightforward. The little red “Shop” button on the Quick Extender Pro home page eluded one of our testers for a moment, so be sure to check the top right corner of your screen if you’re looking to make a purchase. Strangely, this slight difficulty accessing product purchasing pages is more or less universal among penis extender websites.


Rating: 8.9 / 10

Quick Extender Pro’s privacy policy is transparent and honest. It shares information with partners when necessary to fulfill orders, provide customer service, and conduct research. The company doesn't share any private information with third parties without your consent, and its website does not use cookies for tracking. That last point — that Quick Extender Pro doesn’t use cookies for tracking — is unusual and a welcome difference for a site dealing with sensitive sexual information.

When you order through Quick Extender Pro, the resulting charge on your credit card statement comes from INNOVATECH. Not only does this protect you from any insights a person could gain by reading your statement, but it also bears no meaningful search engine connection to Quick Extender Pro. Your purchase would remain a secret even if someone searched the company name.

That last layer of privacy is refreshing. Many such companies obscure their names on credit card reports, but it’s often easy to retrace that name back to the company in question with a simple online search. We were pleased at how much more difficult it was to retrace Innovatech back to Quick Extender Pro.

Customer support

Rating: 8.5 / 10

For the most part, Quick Extender Pro has good customer support. Its library of reference materials — from manuals and FAQs to videos — gives users a great reference point for most questions.

We also found that the company’s chat support has improved over the years. Previous evaluations included some long wait times to speak with an agent, but more recent testing has shown us that Quick Extender Pro’s chat support is much faster in responding than it used to be. We tried to stump them but didn’t have any questions the team there couldn’t answer.

All the other major players in this space lack chat support entirely, with most offering an email form and nothing else. In one case where a phone number was available — through SizeGenetics — it took several tries and long hold times to speak to a representative who ultimately proved incapable of solving our issue. By comparison, Quick Extender Pro offers much better support.

What is Quick Extender Pro?

Quick Extender Pro makes a line of penis extenders that rely on traction for growth. Penis traction is a safe and effective way to achieve enlargement in length and, sometimes, girth. Quick Extender Pro can correct curvature for some men with Peyronie's disease (curvature of the penis that can be painful and inhibit sexual activity). Very severe cases of Peyronie's disease may result in modest improvements, if not complete correction.

In addition to several parts and accessories, the company offers four main products for penis enlargement and straightening:

CostMaximum extensionMaximum tensionBooster Pump
Value Edition$1206”3,000g
Deluxe Standard Edition$1808”3,500g
Deluxe Limited Edition$35012+”4,000g
Curvature & Peyronie’s Edition$1808”4,000g

Depending on which package you choose, you may need to purchase additional accessories to continue using the Quick Extender Pro for the duration of your therapy.

Here's a look at the Quick Extender Pro Deluxe Standard Edition — our top choice for most men — as unboxed and assembled by one of our senior editors:

If you purchase one of these devices, you'll receive it discreetly in the mail and can begin your treatment immediately. The outer packaging does not contain anything identifiable about the nature of its contents; our testers were very satisfied that the box was nondescript. Nobody would know what’s inside of the package.

No matter what extender you buy, it arrives swiftly at your door. Opening it up and using it is a surprisingly simple process. Its main components come preassembled, and you only have to measure yourself and make sure the starting length is correct before you begin.

Is Quick Extender Pro legit?

You should always consider whether a company is above board, particularly when they offer therapeutic devices for sensitive parts of your body. Sketchy companies bombard men with products that promise to enlarge penises in limitless ways and in no time at all.

Quick Extender Pro isn't one of those companies; it’s been in business for over a decade and is a recognized leader in the penis extender space. If you have a question or issue with the product you've purchased, Quick Extender Pro's customer service is excellent. You can easily reach out and speak to a helpful human being.

If you're dissatisfied with the product after six months, you can take advantage of the 6-month money-back guarantee. From our experience, you should do yourself a favor and stay the course for at least several months before drawing conclusions about the results.

Quick Extender Pro’s online reputation

Quick Extender Pro’s online reputation might seem a bit mixed at first, but a closer examination reveals a positive outlook from most customers. The company holds a 4.1-star rating on Trustpilot after 68 reviews at the time of this writing. Most of the negative reviews are associated with issues in international delivery (outside the U.S.).

Quick Extender Pro’s rating with the Better Business Bureau might seem scary (it currently has an F), but the site only has one review for the parent company, Innovatech. And there are only three complaints listed from the past three years. One review and three complaints are not sufficient for drawing any conclusions; given the limited data on BBB, and considering our own experiences with the company, we feel the Trustpilot rating is a closer reflection of reality.

Who is the Quick Extender Pro for?

While most men have close to average penis size, you don’t have to be in the smaller minority to reach for a penis extender like the Quick Extender Pro. A man might want to increase the length of his penis for numerous reasons. You may be interested in providing more pleasure to your partner. You might feel self-conscious enough about your size that you avoid places like locker rooms for fear of being seen. You might just wish your penis was a little bit bigger for your own satisfaction and happiness. Maybe your penis size is the only thing holding you back from a career as an underwear model.

In short, the Quick Extender Pro is appropriate for any man who wants or needs his penis to be a little bit bigger. It’s also a potentially life-altering medical device for men with Peyronie’s disease whose doctors advise them to try it.

Who should consider other options

If your penis is already well above average (more than 5.4 inches when erect), you might not want to make such a stringent time commitment as extension takes. On the flip side, it’s possible to have a penis too small to use the device. Quick Extender Pro doesn’t define this size, but the company advises that you use the least number of extension rods if you’re smaller than the minimum “user size” (which we explain in our “How to use” section below).

However, if your fully outstretched penis isn’t at least two inches long, your glans might not be able to meet the portion of the glans support that holds it in place. And, even then, it might cause those initial few months to be more uncomfortable from a greater degree of traction force than you’d experience if your penis were slightly longer.

For these men, the Phallosan Forte might be a better option. Its belt traction and vacuum pressure combination involves a much shorter minimum distance, which may enhance both comfort and performance.

You should also consider your schedule and whether you can accommodate the daily routine: four to eight hours of wearing the Quick Extender Pro device, for months. Unlike some other extenders, we don’t suggest that you try wearing the Quick Extender Pro while sleeping, so these need to be waking hours of available time.

Lastly, if you have severe Peyronie’s, an extender may be insufficient to treat the problem. Whatever your goals, talking to a doctor before beginning treatment would be wise.

Does Quick Extender Pro work?

Yes, Quick Extender Pro works. When it comes to the effectiveness of its products, Quick Extender Pro can deliver real results based on scientific research.

The company claims that men can grow several inches within two months. We believe these predictions may be inflated based on our research and testing. Studies indicate that penis traction devices produce meaningful results that are somewhat more modest, on average, than what Quick Extender Pro suggests. Results typically approach one inch in extension but rarely exceed it.

Our testers were pleased to notice an increase in size after several weeks of following the Quick Extender Pro routine (close to the one-month mark). By month 2, enlargement was in the vicinity of a half-inch for most of them.

Insider Tip: Based on all of the anecdotal evidence we’ve found, we would caution that any gains you experience could be temporary if you use a Quick Extender Pro device for fewer than 12 weeks. In other words, even if you’re satisfied by gains you make prior to a 3-month usage, we’d recommend you consider those gains impermanent.

Throughout the test, our testers averaged about 0.8 inches of growth in length — and an average 0.25-inch gain in girth, measured at the glans — after testing for five months. A few men reported gains of one inch in length and close to a third of an inch in glans girth after six months, while a couple others experienced close to 0.65 inches of total gains in length and scant gains in girth (less than a tenth of an inch).

When you use them as directed, you can expect enlargement with Quick Extender Pro’s products — more in the range of a half-inch to one inch of growth, based on our testing and analysis of studies. For many men, these results will be well worth the relatively low price and the time investment. On top of that, once you make these gains and use Quick Extender Pro for more than three months straight, you don't have to continue doing the daily extender routine to maintain the improvement.

Both anecdotal and clinical study results suggest that most men will find satisfaction in the results of using a penis extender like Quick Extender Pro.

How does Quick Extender Pro work?

The Quick Extender Pro line of products uses the principles of penis traction to apply a persistent, controlled stretching action to the shaft of the penis. Because this therapeutic approach requires that you wear the device for a few hours daily, the product design must allow for a comfortable and secure fit.

One thing that keeps many men dedicated and on track with their routine is that the results are permanent. After using a Quick Extender Pro traction device for at least 12 weeks, whatever gains you have made in penis size will endure, and you can stop using the device permanently whenever you're satisfied.

Here's a step-by-step breakdown of the process.

Step 1: Buy and wear the Quick Extender Pro as instructed

Make sure to set up your device properly and wear it as directed. We have a section dedicated to set-up below.

For penis traction to work well, plan to wear the extender device daily for at least a couple of hours. Most men will take a day off for recovery from time to time. Listen to your body and consider your timeline goals to achieve success, but don't exceed the rigors of the programs that the company suggests.

The device causes what feels like a light, persistent stretching — an initially strange sensation but one that isn't uncomfortable; you get used to it quickly.

Step 2: Quick Extender Pro promotes blood flow and creates microscopic tears in the penis.

This doesn't sound like a constructive or pleasant experience, but how the body repairs those microtears is really what will produce the growth. Microtearing should be both painless and invisible to the naked eye. If you experience bruising, you need to slow down your therapy because that indicates you're moving too fast, the tension is set too high, or your sessions are too long.

Step 3: In repairing the microtears, your body enlarges your penis.

Your body responds to the microtears with new tissue growth through the processes of mitosis and cytokinesis. Cells divide to create two cells identical to the first, and they do this many times until the microtears repair. Microtears that lead to tissue growth may sound odd until you consider how we build muscle mass during properly designed workouts.

How Quick Extender Pro can treat Peyronie’s disease

Penile traction therapy has been the subject of several clinical studies looking at its potential to treat Peyronie’s disease, a significant curvature of the penis that makes intercourse difficult and sometimes painful. Extreme cases can interfere with daily life.

Several studies indicate that penile traction using devices like the Quick Extender Pro is effective at straightening out the penis over time. Men in these studies also experienced an increase in penis length.

Quick Extender Pro has a dedicated model for use by men with Peyronie’s disease, which is specifically calibrated to reduce curvature. It costs the same as the Deluxe Standard Edition, and the packages are very similar, but the Peyronie’s model offers greater spring tension.

How to set up and use Quick Extender Pro

Despite a few moving parts, Quick Extender Pro is relatively easy to use. Our testers found it easy to set up and get themselves situated in the device, and making adjustments as needed was also a straightforward process.

Below is a picture labeling the different component parts for this extender device.

Penis extenders can be confusing to use at first. To help, we’ve created this tutorial video using an anatomical model of a flaccid penis; it shows you how to wear the assembled device.

Youtube Video

Here’s a quick, written step-by-step summary of those steps to using the Quick Extender Pro:

  1. Determine the starting length for treatment. Quick Extender Pro calls this the “user size,” and it’s determined by subtracting 1.6 inches from the length of your penis at erection. So, for example, if your penis measures 5.6 inches when erect, your user size would be four inches.
  2. Add or subtract extension rods from the device until its length (from the base of the base ring to the tip of the last extension rod) matches your user size.
  3. Attach the glans support, which pushes into place. Be sure that it’s right-side-up. The groove that supports your glans should be facing up, and the extension bars should be able to flex upward, not downward.
  4. Take two of the silicone tubes and feed them into their foam sheathes.
  5. Wrap a small amount of gauze or cotton around the head of your penis.
  6. Insert your penis through the base ring.
  7. Place either end of one silicone tube into one set of left and right holes in the glans support, creating a loop.
  8. Push the glans support toward your body, depressing the spring mechanism so the support is as close to your body as possible.
  9. Gently feed your penis through the loop made by the silicone tube.
  10. Pull on the ends of the silicone tube to tighten the loop around your glans. You don’t want to strangle your penis here, but it should be tight enough to keep the glans in place.
  11. Repeat steps 7-10 with a second silicone tube.
  12. Gently release the glans support, allowing the device to come to extension.
  13. Wear the device for a prescribed period based on your comfort and goals.

Quick Extender Pro recommends one of two regimens for most men.

Regimen A (recommended for most men)Regimen B
Daily usage time8 hours4 hours
Increase extension by0.5cm0.5cm
Rate of extension increaseEvery 7 daysEvery 14 days

If you find that your user size falls between two available device lengths based on the size of additional extension rods, we recommend that you err on the side of the smaller measurement. It’s smarter to be patient with the treatment than to try to rush it and injure yourself, which would ultimately set back your progress.

Is Quick Extender Pro's penis traction safe?

The short answer is yes, Quick Extender Pro's penis traction is safe, provided that you use it as directed and approach the treatment with a healthy level of respect. Don't try to go too fast or be too aggressive with treatment. Start modestly and build up to greater extension levels or longer sessions. As long as you listen to your body and don't misuse the device, you will experience safe and comfortable success.

Stretching the penis to cause microtears and enlargement requires patience. Consider the experience of working out to build muscle: if you were just beginning to lift weights, you probably wouldn't start by bench-pressing 300 pounds.

If you cut corners and try to go faster with greater tension and longer sessions, you could make the process uncomfortable at the least. You could also bruise your penis, cause some bleeding, or even cause more severe damage that requires medical attention.

But as long as you remain patient, listen to the signals your body is sending you, and follow the directions to use it properly, the Quick Extender Pro is safe and effective.

Quick Extender Pro pricing and packages

You have four options when buying a penis extender from Quick Extender Pro.

  • Value Edition: $120
  • Deluxe Standard Edition: $180
  • Deluxe Limited Edition: $350
  • Peyronie’s Edition: $180

All four of the Quick Extender Pro options feature the company's Double-Strap System (DSS), a pair of silicon tubes designed to enhance comfort with long periods of use and address issues men experienced in the past with inferior penis traction devices. Older models of penis extenders put unnecessary tension on various parts of the shaft or caused slipping and chafing when worn for extended periods.

Quick Extender Pro makes its models out of medical-grade materials, which means that the plastics, aluminum, and other materials comport with durability standards that promote safety among devices like stethoscopes, for instance. The purpose of designating materials as medical grade is to provide assurances that the device will be strong enough to fulfill its purpose safely and also safe for the amount of human contact it was designed to provide. In this case, that means that the materials are hypoallergenic and aren't as susceptible as other surfaces would be to harboring bacteria that could cause infection. Most recommendable penis extenders use high-quality materials, but it's worth noting when a product is built with materials that meet those standards for durability in medical situations involving body moisture and frequent, long usage.

With each package, you get an instructive DVD and a self-measuring chart to organize and track your progress, along with a handy tape measurer to help you. And every package has a warranty that protects you if the device breaks.

There are differences between the available packages, however. The most meaningful differences involve maximum length and tension, as well as how many accessories come included.

Companies like SizeGenetics offer similar packages with added extension rods and comfort materials as you spend more money. But our testers had some difficulty getting the right number of extension rods to match a purchased package from SizeGenetics, and we found Quick Extender Pro to be the more reliable company overall.

Other products, like Phallosan and PeniMaster, have a primary base device onto which you can add various accessories to increase tension or performance. These systems get expensive quickly compared to Quick Extender Pro, which only needs added extension rods to increase performance.

Deluxe Standard Edition

PRICE: $180

For the money, the Deluxe Standard Edition is Quick Extender Pro's Goldilocks package, offering the best value for most men. It includes:

  • Base extension device
  • 3,500g tension springs
  • Six silicone tubes
  • Six comfort pads
  • Four large extension bars
  • Two medium extension bars
  • Six small extension bars
  • Zippered hardshell case
  • Travel pouch
  • Measuring tape
  • One-year warranty
  • 6-month money-back guarantee

The Deluxe Standard Edition comes with fewer replacement parts than the Deluxe Limited Edition does. Still, replacement parts for the Quick Extender Pro are affordable, so those particular additions don't exactly make the more expensive package worth the added cost. For most men, the 3,500g of tension weight will be plenty of tension for successful therapy.

Deluxe Limited Edition

PRICE: $350

This package contains more replacement parts and a higher tension potential than any other package from Quick Extender Pro. It's bigger, more powerful, and more comprehensive than the rest.

  • Base extension device
  • 4,000g tension springs
  • 12 silicone tubes
  • 12 comfort pads
  • Four large extension bars
  • Two medium extension bars
  • Six small extension bars
  • Vacuum booster pump
  • Replacement springs
  • Mahogany storage box
  • Travel pouch
  • Instructional DVD
  • Measuring tape
  • Lifetime warranty
  • 6-month money-back guarantee

Featuring the maximum amount of tension that Quick Extender Pro provides (4,000g), the Deluxe Limited Edition has the power to help you achieve the fastest results, whether you're looking to straighten a curving penis or enlarge your penis (or both). Quick Extender Pro estimates that you can gain as much as an additional inch in length in the same period compared to the Deluxe Standard Edition (the second-tier offering).

(We'd like to offer some advice, though: just because a device can provide the maximum tension weight doesn't mean you should necessarily utilize it rapidly and as aggressively as you'd like. Be patient and start gradually to use the Deluxe Limited Edition safely and effectively.)

The Deluxe Limited Edition also comes with an attractive wooden storage case and a booster pump that many men love. While some men experience more growth in length than girth, the addition of vacuum pressure can help improve gains in girth, as well. This package comes with enough extender supplies to accommodate lengthier penises (even upwards of 12 inches). Additionally, you'll receive a whole set of informative DVDs focused on sexual health and satisfaction.

We'd recommend the Deluxe Limited Edition, particularly for men with curvature and a desire to enlarge their penis. If you lack curvature and don't mind placing additional orders, you could also be very well-served with the less expensive Deluxe Standard Edition.

Value Edition

PRICE: $120

If you're on a tight budget, the Quick Extender Pro Value Edition might be your ideal solution.

  • Base extension device
  • 3,000g tension springs
  • Two silicone tubes
  • Two comfort pads
  • Two medium extension bars
  • Six small extension bars
  • Travel pouch
  • Measuring tape
  • Extended warranty
  • 6-month money-back guarantee

At 3,000g, its tension springs lack the tension weight of the others. Still, this is 200g more than competitors like SizeGenetics offer at a similar package level. The Value Edition also strips away all niceties from the bigger, more extensive packages – no more DVD sets or protective carrying cases. Most notably, it reduces the number of replacement accessories across the board, which means you'll soon have to buy more supplies from Quick Extender Pro. Note that it can accommodate lengths of up to 6 inches.

In our opinion, it would be wiser to invest the additional $60 into the Deluxe Standard Edition if you can. If not, however, this package will get you started on the path to penis enlargement. Whichever package your budget can allow, we believe you'll see positive results if you use Quick Extender Pro as directed.

Curvature & Peyronie's Edition

PRICE: $180

Designed specifically for men dealing with penis curvature or Peyronie's disease, this device is equipped with tension springs calibrated for maximum therapeutic benefit to address these conditions.

Penis traction is a proven method for addressing penis curvature and helping men with Peyronie's disease. For many men, the Curvature & Peyronie's Edition can help immensely, though severe instances of curvature may not be fully fixable by the Quick Extender Pro. It features:

  • Base extension device
  • 4,000g tension springs
  • Six comfort pads
  • Six silicon tubes
  • Four large extension bars
  • Two medium extension bars
  • Six small extension bars
  • Zippered carrying case
  • Replacement springs
  • Travel pouch
  • Instructional DVD
  • Measuring tape
  • One-year warranty
  • 6-month money-back guarantee

Spare parts and accessories

Quick Extender Pro offers a line of spare parts and accessories you can use to maintain your device and increase its length beyond what’s capable with your package contents. These include 3,500g and 4,000g spring replacements, added extension bars, and comfort materials like foam sheathes.

Some of Quick Extender Pro’s competitors have a greater array of accessories, like PeniMaster’s weight set and SizeGenetics’ added gauze and cotton padding. For the most part, these are materials you can get at most pharmacies, though it is convenient to get them from the manufacturer.

Quick Extender Pro return policy

Quick Extender Pro offers a 6-month money-back guarantee on its products, so if you use it consistently and don't see results, you can get your money back. This is vastly superior to the other companies in the space. For example, SizeGenetics, MaleEdge, and JES Extender all offer a money-back guarantee through their parent company, DanaMedic. But that guarantee is full of holes.

For starters, DanaMedic will only honor the guarantee if you submit before and after photos of your penis to prove the device doesn't work. We find this policy to be invasive and unnecessary. You also have to sign up for the company's Diary and make weekly entries of your measurements. But this information is buried in the terms and conditions, and 99% of users will likely never see it. What's worse is that, in testing, our team found it impossible to sign up for the Diary in the first place. When we attempted to create accounts, we were stopped by a verification step and told to check our email. No verification emails ever came.

PeniMaster has a more honest guarantee, but it's too short at just one month. That's not enough time for men to notice any results from extension. And Phallosan has no such guarantee to speak of. Ultimately, if you want security in your purchase against the possibility, however small, that extension won't work for you, Quick Extender Pro is clearly your best choice.

How Quick Extender Pro stacks up against the competition


At first glance, you can see remarkable similarities in what SizeGenetics offers compared to Quick Extender Pro. The hardware is very similar, though the straps used to hold the head of the penis against the glans support are noticeably different. SizeGenetics also offers a lot less for the money in terms of extras.

Perhaps most importantly, SizeGenetics falls short when it comes to customer service. One of our testers received an incomplete package, and the phone and email systems for restitution were overcomplicated and unfair. Quick Extender Pro offers a superior product based on the same principles for less money.

PeniMaster Pro

PeniMaster Pro isn't the least expensive option out there, but it does win serious points for comfort. Its device utilizes an extension bar system similar to that of Quick Extender Pro, but instead of strapping the head of your penis into place, it employs a suction device to support the glans and keep it firmly in place. PeniMaster Pro’s extender is a little more confusing to learn than Quick Extender Pro, and some men might not be as comfortable using vacuum suction as they are also using extension. Still, PeniMaster Pro is a serious option if you don't mind complicated devices.

Ultimately, we still believe Quick Extender Pro is the superior choice for its effectiveness, simplicity, and cost. Check out our PeniMaster Pro review for more information.


MaleEdge is a decent option for the budget-conscious or those who want to start out with less stretching force than you get with Quick Extender Pro’s least powerful model. It’s also a little more complicated to put on each time you want to use it. Construction quality isn’t quite what you get from much of the competition, but you might be fine if you’re gentle with the product and don’t travel with it too much. However, the price-to-power ratio with Quick Extender Pro is simply superior.

Jes Extender

This company makes some of the most expensive traction devices out there, but there isn’t much evidence that any difference in build or function justifies the cost. Its smallest extension bars are 0.5 inches compared to the 0.1-inch bars available with Quick Extender Pro devices. That means that upward adjustments with the Jex Extender are more drastic and can result in added discomfort compared to Quick Extender Pro’s gradual design. So, for comfort and value, we still prefer Quick Extender Pro.

Phallosan Forte

The Phallosan Forte removes a lot of the guesswork that comes with measuring your penis and sizing it up with just the right number of extension bars. It’s a more expensive product, and initial assembly can be challenging, but once you figure it out, it offers one of the most comfortable extension experiences available. It also offers more position options for your penis during traction, which makes it one of the better options to hide under clothing and even wear while sleeping.

It also combines traction and vacuum pressure, which one study shows can enhance both length and girth, the latter measure being something that traction-only devices sometimes struggle to increase.

Are there any alternatives to penis traction?

The only viable alternative to penis traction for men seeking to elongate their penises would be surgery. Doctors offer surgical options to help men achieve a longer or wider penis. However, besides being much more expensive than Quick Extender Pro, these procedures are painful and carry the risk of unpleasant or dangerous side effects.

To lengthen the penis, a surgeon may sever the suspensory ligament in the penis in an operation called ligamentolysis. The suspensory ligament is what anchors the penis to your pubic bone. Cutting it can indeed make a flaccid penis look longer (1-3 centimeters, generally) because it's no longer connected to the pubic bone. However, the outcomes for this surgical procedure are mixed. Men and their partners are only 30-60% satisfied with their sexual performance after surgery. Some men actually experience a shortening of their penis, while others have difficulty during intercourse because the penis no longer has the positional stability that came from being attached to the pubic bone.

To improve girth, surgeons may inject tissue into the penis – tissue coming either from your own body or from a cadaver. The surgeon essentially rolls this tissue around the shaft, directly beneath the skin of the penis. Though it's technically sterile, cadaver tissue used in penis surgery is an "off-label" application of that substance and may cause infection and necrosis of the skin.

We strongly encourage you to try penis traction before considering surgery, and the Quick Extender Pro is a great choice.

For men with Peyronie’s disease, there are a few other treatment options on the market, including injections of an enzyme that dismantles collagen. But that treatment is often followed immediately by traction-based stretching, first within a urologist’s office and then at home with a traction device like the Quick Extender Pro. And, according to Endo Pharmaceuticals, the company that manufactures the branded form of the enzyme injections, side effects can include penile corporal rupture (fractured penis, which can result in:

  • A popping sound or sensation in an erect penis
  • Sudden loss of the ability to maintain an erection
  • Pain in your penis
  • Purple bruising and swelling of your penis
  • Difficulty urinating or blood in the urine

Urologists may also prescribe pentoxifylline, which some studies have shown to be effective at stopping Peyronie’s from worsening and improving outcomes in some patients, especially when combined with other treatments, including traction.

FAQ about Quick Extender Pro

Final takeaway

Given the fact that Quick Extender Pro uses a method of penile traction therapy that has successfully lengthened penises in human studies, and considering that the company has the best money-back guarantee and one of the best prices around, it makes sense for most men interested in penis enlargement to start here. The process is long and requires commitment regardless of which company’s product you choose, but based on our research and testing, Quick Extender Pro seems to be the best extender device for most men.
