Top Penis Extenders in 2017 + Things You Need to Know

Please read: There is a lot of false advertising going on at review sites and forums, so I would like to clarify a few points first (more information and FAQ can be found further down the page).

  1. Results of penile traction therapy (penile stretching) vary for each individual and success is not guaranteed! Gains will depend on how well your body responds and complies to external stimulation, and some users may not achieve any significant results.
  2. All stretching devices deliver similar results. There is no extender that will give you 'better' or 'faster' or 'bigger' results than others. As long as it is functional, it is then up to your body's compliance.
  3. Some devices are relatively more comfortable than others, but you will experience some degree of discomfort with all devices. The claim that you can wear it for hours without feeling anything is an overexaggeration.
  4. Do not trust any before & after pictures on review websites! Users who have achieved results do not need to prove anything to anyone. Most 'proof' photos published online are fake/dishonest and used to market a certain product.
  5. Do not be suckered by guarantees of adding 3-4 inches to your manhood. Most users do not gain more than 1 inch in length, if any.

Which Penis Extender is Best?

Choosing between the many products on the market can be confusing. At the end of the day, all extenders have the same fundamental working mechanism, but there are a few things you should take into account when buying a new device.

Comfort is the most crucial feature to look for. You can buy a penis extender made of gold (really, some devices are gold coated!), but if it's not comfortable to wear for long hours then it'll be useless. Other considerations are quality, spare parts, company reputation, customer support, and of course, price.

Here is a quick review of the top penis extenders found on the market today.

PeniMaster PRO Rod & Belt Stretcher

PeniMaster PRO

(official website)

PeniMaster PRO is a dark horse among penis extenders. It is not as popular as other brands, but most users who have had the chance to try it would agree that it excels over many devices for two main reasons: it is of decent quality, and it is quite comfortable to wear.

Unlike most other devices that use a strap wrapped around the glans to pull the penis, PeniMaster PRO comes with an air-sealed head attachment that sticks to the glans by vacuum suction force. Pulling your shaft with this tool is more comfortable and less likely to block circulation to your glans as opposed to using a strap.

PeniMaster PRO can either be used as a traction device using the rod extender, or as a belt stretcher using the adjustable belt. The rod extender is more effective in my opinion since the tension you get with it remains constant, while the belt can lose tension as your body moves. The belt is still helpful if you'd like to stretch your penis sideways, and it's more convenient to wear under your clothes. The good news is you can get both of them in the complete set package for a good price.

PeniMaster PRO is manufactured in Germany and sold by MSP Concept GmbH & Co.

Price: $282 for the rod extender, $259 for the belt stretcher, and $327 for the complete set package (rod extender & belt).

PMP is the best documented penis extender I have seen so far. The official website contains many instructional articles and demonstrative videos. It may not be the easiest device to learn how to use properly but the company does a fine job at providing all the instructions you will need to get started. This shows that they actually care about their customers, unlike others that do not provide proper usage instructions and will not even bother replying to your emails after you make the purchase. The following are some videos of PeniMaster PRO that demonstrate how to use it.

X4 Labs Premium Edition Package

X4 Labs Extender

(official website)

X4 Labs is another decent product that stands out from the crowd with its comfort straps and quad support system, which allows you to use a combination of two fasteners for extra comfort and safety. There are three different types of glans fasteners that come with X4 Labs: rubber straps, Velcro straps, and silicone tube harnesses.

This device comes with a wide range of additional enhancement and spare parts. It comes in several packages with various useful accessories. But what really makes X4 Labs a better choice than many of the competitors is its relatively low price, yet high quality. The Premium Edition (shown in the picture above) costs $120 and beats many other overpriced devices.

X4 Labs fits a wide range of penis sizes from as small as 1 inch in length! Most other devices only work for men with a 4+ inch penis, but with the optional Mini Quad Support piece, this extender is especially recommended for men with a small penis.

If you are a beginner and just looking for a good device to try out penile traction therapy, X4 Labs is the perfect tool to start with. If you are an experienced user, they also have advanced packages with high tension springs and many extras.

X4 Labs extender is made and sold by Canadian X4 Labs Inc.

Price ranges from $90 for the Deluxe Edition up to $270 for the Gold Luxury Edition.

The following videos show the three different types of fasteners that come with X4 Labs. Keep in mind that each package comes with a different number and types of fasteners.

Update: I have seen several customer complaints about X4 Labs support not responding to emails. I'd still recommend this product since it is real, functional, and the price beats most competitors'. Service is good as long as everything goes as it's supposed to, but if something goes wrong with shipping or returning, then you may have a hard time with their support. Also, they have a lengthy and complicated return policy so make sure you read it carefully before placing an order.

Jes Extender Gold Standard

Jes Extender

(official website)

Jes Extender is one of the oldest brands in the market. It is the original penis extender that became the standard design for all strap and noose extenders. If you have heard about the hyped-up SizeGenetics, well, it is just a rebranded version of Jes Extender.

This is a high quality device and clinically proven to work. It comes with a rubber strap fastener and a protection pad. There are also other optional comfort-enhancing accessories.

Jes Extender is manufactured in Denmark and sold by DanaMedic.

Price ranges from $209.99 to $1,000.00 (six different packages with varying features and parts).

Phallosan Forte Belt Stretcher Package

Phallosan Forte

(official website)

Phallosan Forte is not a traction-based extender, but rather it uses an elastic belt to deliver the pulling force on the penis. The head attachment uses vacuum force to secure itself around the glans.

This is similar to the belt system of PeniMaster PRO, but Phallosan Forte comes with an indicator that shows the amount of tension being applied. Phallosan Forte is more comfortable than strap and noose extenders, but has some considerable disadvantages, like the lack of a rod traction system which is more effective and consistent, and its high price.

Phallosan Forte is manufactured in Malta and sold by Swiss Sana Anstalt.

Price: $339.

New SizeGenetics Ultimate System


(official website)

Surprised to see this one in last place? Well, it would seem that SizeGenetics is the very best penis extender you could buy, given the oodles of rave reviews trying to convince you how great of a deal it is and impressive the results are! But what you may not know is that 99% of those reviews are created by affiliate marketers just trying to sell more.

You see, SizeGenetics was one of the first products in the male enhancement industry to offer generous commissions to affiliates who promote their device, and it simply became '#1' because that is what most online 'reviews' are trying hard to 'sell'.

I am not saying that it is a bad product, but it is cunningly played up. Despite the marketing BS and questionable before/after pictures, the device itself is functional and can get the job done.

SizeGenetics is made and sold by DanaMedic ApS (Denmark).

The price of the SizeGenetics Value Edition is $199.95. The Comfort Package costs $249.95, and the Ultimate System will run you $299.95.

What Exactly is a Penis Extender?

An extender or traction device for the penis is a small tool that can be worn on the penis to stretch it with constant tension force.

Penile traction is not officially recognized as a treatment for small penis or micropenis, but there have been a few clinical studies that proved the efficacy of extenders in lengthening the penis.

The use of penis extenders is the only non-surgical method of penis enlargement that may produce significant results.

How is a Penis Extender Used?

There are different suggested routines, and some also recommend performing manual penis exercises to maximize gains. You should refer to your product's manual for recommended usage instructions.

But generally, you will have to wear the extender for a minimum of 6 hours and a maximum of 12 hours a day, 4-6 days a week.

Most devices are small and flexible enough to be worn under clothes, which will allow you to perform your daily activities while wearing the concealed extender. But this is only practical for men whose job does not require a lot of physical movement.

It is important that new users start with a gradual stretching routine until their penis is ready to endure long hours of continuous stretching. For example, first week: 1-2 hours; second week: 2-3 hours; third week: 3-4 hours; fourth week: 4-6 hours.

Again, your product should come with more details on how to use it properly.

What Results Can You Get?

As clinically shown, after about 6 months of traction therapy you can expect an increase of up to one inch in penis length. Some users keep going for one year or more, and there are unverified claims of more than 2 inches of growth.

Some important notes to keep in mind:

  • It is unclear whether the enlargement occurs due to tissue growth or as a result of stretching out the portion of the penile shaft that is hidden inside the body.
  • Results vary for each individual. Effectiveness depends on how well your body responds to external stimulation, so not everyone may see significant results.
  • Extenders only increase penile length but not girth. Some users also perform manual penis exercises to promote girth enlargement.
  • Penis extenders may help improve penile curvature. They are not an approved treatment for Peyronie's disease, but some patients saw improvement.
  • Most online reviews are overdrawn and created by marketers. Misleading before/after pictures is a common tactic to lure in customers. So, NO, your dick won't become 3 inches bigger in just a few months!

Be advised: A penis extender will not (for sure) increase your penis size. It may increase your penis size. The efficacy of this technique depends on each individual body's compliance, and some users may not achieve any results after months of use. Younger men (16-30 years old) are more likely to have success with penis extenders, and while there is no specific age restriction, I would not recommend this method to men over 40 as it may not yield significant results.

Are Penis Extenders Safe?

Nothing is safe unless used safely! If you apply too much tension force on your shaft you can cause damage to erectile tissue, blood vessels and/or nerves. A warning sign of dangerous use is constant pain or numbness in the penis.

It is normal to feel a little discomfort while wearing the device, but it should not be painful. If you experience remarkable pain in the penis it means you are applying too much traction force or something else is wrong. That may cause damage to your penile tissue and lead to shrinkage instead of enlargement.

Another thing you have to watch out for is not blocking circulation to your glans. This is a common risk with low quality devices that do not come with comfort padding for the strap and will just 'choke' your glans. You should remove the device every hour or so to restore blood flow to the glans in case circulation gets blocked or reduced.

Vacuum Head Attachment vs. Strap Fastener

There are two types of penis stretching devices that are commonly used; those which have a vacuum head attachment, and those with a rubber strap or silicone noose fastener.

Devices that use a vacuum head attachment - like PeniMaster PRO - are the newest on the market, and they have proved to be considerably more comfortable and secure than strap/noose-based extenders.

However, some users still prefer the conventional devices that come with a strap, noose, and/or Velcro fastener. They both work well once you figure out the most comfortable setting for you, but you will likely be hassling with more slippage issues when using a strap or noose. Vacuum fasteners may also slip off, but much less often.
