Dan Crispin, August 21, 2018

Hands down best price. Finally glad to see an extender that's affordable. I didn't fit well into Phallosan, so it was nice to have one-size fits all with PhalloGauge. I'm uncircumcised (uncut) so I'm glad the double-grip method works so well with PhalloGauge. Definitely recommend if you've been frustrated with other penis extenders. Perfect for to make the ladies exciteds.

What Women Think:

"The average size increases make my lover's cock truly fantastic and make me cum even harder."

"It's no laughing matter - this extender is a lot like finding a pot of gold at the end of the rainbow."

"Thank fuck things are different now - hotter, steamier, orgasmic, sexier."

User Reviews

4 star review

Judd Salvio, September 7, 2018

A bit pricy but definitely worth it. I first tried SizeGenetics and Phallosan. Phallosan's condom parts didn't fit my penis well, so it always slipped off. The SizeGenetics was OK, but I got the cheap version and the noose part always choked out my penis. Not to mention I'm uncircumcised and I had issues getting it stay on. Sizedoctor did not have any of these issues, so I'm glad I switched over and finally found an extender that's not wasting my time.

What Sexual Women Think:

"Giant, harder erections from the penis stretcher - what more could a woman ask for!"

"My pussy is very picky on which cock it will take nowadays - only the ones that stretch me are the ones I let through."

"What could be better than a massive cock finally fulfilling my deepest sexual fantasies."

"My partner had me squirting plus got me so wet - it was erotic."

"This penis extender was better than a sex toy - It made me cum all over his bed."

"Now I always make sure I'm wearing hot underwear. I've got to stay sexy for when he comes home and takes the penis extender off."

"Now he's better than my favorite luxury vibrator, it makes me secretly happy now that things are steamy and heating up."

"Cumming four times every night, I simply collapse from all the hot pleasure. It's all part of the fun."

"He makes me beg now. Not surprising since he can detect how wet I get."

Phallosan's Big Problem: Sizing Issues

Each Phallosan comes with a small, medium and large condom part.

Phallosan condom part also breaks easily.

However, most men will find they will not fit perfectly into one of the three freaky sizes.

If the part is too small, it chokes your penis. If it's too big, your penis slips out of the device.

How Do Penis Extenders Work?

Medical penis extenders that utilize penile traction therapy have drastically reduced the demand for penile surgeries because the traction utilized is not only 75% more effective, it is much safer.

These results have been well-documented in the BJUI by Dr. M. Oderda and Dr. P. Gontero and by the 2013 edition of the Journal of Sexual Medicine. Both sources found that extender devices lengthen the average length by at least 0.7 inches over the course of 12 weeks.

Are there health side-effects when wearing penis extenders?

Most manufacturers give instructions on how to use the product safely. As long as you make sure to use the extenders as intended, these devices will not cause any potential health problems.

It has also been reported that after a study conducted with 55 male participants, not one subject has suffered any health issues.

As of this time, we can safely report that penis extenders are safe to use.

Reports on Utilizing Penile Traction Therapy to Treat Peyronie’s Disease

Peyronie’s Disease is a medical condition which is definied as an abnormal in the penis shaft.

It's a common problem that afflicts about 25% of men in the United States, with varying severity: Some cases benign, some invasive.

Many doctors have reported that using a penis extender over the course of a 6-8 months can straighten the penis safely, effectively treating complications due to Peyronie's Disease.

Modern medical and technological advancements lead to the discovery of "penile traction therapy" which is the most commonly prescribed therapy to treat Peyronie’s Disease.

As a result, many afflicted men from all over the world can now straighten their penis by engaging in said therapy by using the penis extender devices mentioned in this review.

The amount of documented surgeries for Peyronie's Disease has dropped drastically from about 10,000 procedures each year to about 5,000 - a nearly 50% drop.

About 300 men ages 21-55 were required to undergo corrective cosmetic surgery to correct an accutely bent penis.

More Useful Information to Help You Figure Out the Best Extender for You:

Here's more in-depth details on the PhalloGauge Extender:

#1. PhalloGauge Penis Extender™

The PhalloGauge Penis Extender glamor shot

Here are the reasons why it is one of the best penis extenders for length:

  • It is completely invisible when worn.

  • It is one-size-fits all. No tightening or loosening sizing problems.

  • Designed for both circumcised and uncircumcised men (double-grip technology).

  • Awesome, unbeatable price.

The PhalloGauge eliminates slippage with, stretchy silicone "double-grip" wrap technology.

To see more reasons on how the PhalloGauge penis extender has improved upon length size technology check out this page here.

At $115, there's no denying that the attractive price of the PhalloGauge is the best of all the best penis extending devices.

#2. PhalloSan Forte

PhalloSan is similar to PhalloGauge but is definitely not the best penis extender.

Phallosan uses a vacuum condom to hold the penis glans in place to extend.

Issues I found with the PhalloSan.

Some male user reviews have reported irritation and at the tip of the penile glans due to the Phallosan vacuum.

The Phallosan vacuum is a neat idea, however, some men's penises are just too sensitive and can't handle it.

For this reason, we cannot accept it as the best penis extender.

Here we cut open the pieces of the Phallosan for analysis.
Here, we cut open the parts of the PhalloSan to see what it is made of.

Vacuum Condom Penile Sizes are Functionally Questionable.

PhalloSan extenders come in 3 different silicone sizes - small, medium, and large.

For example, I chose a "medium" size because "small" size was way too tight on my penis and it was painful.

One problem I soon found, is that men might actually fit between sizes.

For example, I fit between a small and medium Phallosan silicone part size.

As a result, the extender kept slipping off.

This is a problem that that doesn't happen with the best penis extenders.

Finding one best size is a challenge.

Does PhalloSan Have the Best Price? Heck no.

Phallosan is well over $300. Yikes.

And that doesn't even include shipping costs (which are also high because they ship from Switzerland.

Given the penis issues I ran into, it is hard to truly recommend this extender to men. Don't buy.

#3. SizeGenetics

SizeGenetics is actually not that bad. But is still definitely not the best penis extender.

Sizegenetics is essentially a size toy like the Jes Extender and X4labs extenders.

But the SizeGenetics is more popular than the x4labs extenders.

There are a few penis problems with Sizegenetics.

In fact, it's probably the best one out of the old length extenders.

One thing we will say is that the noose system is probably the most comfortable out of the rod extenders.

The $200+ price point is a bit tough though.

Extender Parts and Material Quality Are Important.

SizeGenetics rod are made out of steel.

The toy plasic device parts that make up the frame of the extender are decent. The springs are also decent.

Like all toy springs, they will eventually wear out so a replacement SizeGenetics may be required.

Not ideal for the best penis extender review rating, though.

#4. The PeniMaster Pro Extender

The Penimaster Pro extender is an interesting, and uniquely comfortable extender device. It is manufactured in Germany, and as such, the quality is quite high.

How it works: The extender uses it's top suction headpiece part to attach to your penis glans. Once attached, it stretches your penis by deploying the belt system or extension rods.

These dual capabilities is unique only to the PeniMaster Pro extender.

Based on other verified customer reviews, we can report that the PeniMaster Pro has satisfied many users.


  • Fits all penis sizes (length and girth). With its dual-rod system, the Penimaster Pro can accommodate many different shapes and sizes of penises while simultaneously providing a large tension settings range.

  • Fantastic flexibility - Use it as a normal extender with rods or as an all-day stretcher with the tugging belt system. Users can also opt to apply weights to the device.

  • Works with different penile glans shapes - There is a varied choice of headpieces, which provides the user many variable fitting sizes to accommodate men with large and small glans. This part will also work for men with uncircumcised and circumcised penises. These parts also come with protection for the frenulum.

  • 24-Hour Comfort - You’ll be using vacuum bulb-piece and headpiece, instead of hard nooses and plastic straps that can bruise your penis skin from rubbing. This feature of the Penimaster Pro makes it able to be used for at least 8 hours each day.


  • Extra parts are required - The latex parts and diaphragms rubber parts must to be replaced every 14 days, especially for those who are using Penimaster Pro for at least 8 hours a day.

  • If you prefer a more laidback pressure control functionality, you may opt to buy the additional air hose part.

  • Very Expensive - The Price is €289 for the whole system (which includes rods, belts, headpiece, base, and bulb pump)

Warranty: 1 year.

Expected Growth: Min: Adds 0.75 inches in length when used for at least 500 hours.

Money-Back guarantee: 2 Weeks.

Manufacturer: MSP Concept GmbH & CO. KG. (Germany)

Official Website: https://www.penimaster.com/

#5. The Quick Extender Pro

This is a prototype extender model which uses two rods to perform penile traction therapy.

Unlike the Phallosan Forte and PeniMaster Pro, it does not utilize vacuum suction to hold and a belt system to stretch.

Regardless, comfort is still present thanks to its novel two-strap system. Not only that, but it is also much quicker and simpler to take off and put on.

Based on other verified Quick Extender Pro reviews, they have reported high user-satisfaction.


  • Accommodates all penis sizes. It can fit to any penis length by adjusting the two rods.

  • Marginal boosts in wearability and comfort. Of the many extenders with rods, the Quick Extender Pro demonstrates shows its comfort features by way of the "Dual Strap System". It’s a comfort feature unique to this extender brand. It works by spreading the tension across the tip and along shaft.

  • Medical Grade Materials: Lightweight plastics and aluminum. Users won't feel any weight when wearing the Quick Extender Pro. This extender is also safe for men with allergic reactions, so it can be used for a long time.


  • Expensive Price: $119 (Value Pack) to $350 (Deluxe Pack)

  • Lacks the comfort provided by belt-stretching extender types, especially if you expect to sleep and use this extender simultaneously.

  • Lacks Memory Foam - as a result, it may be too harsh on the penis skin.

Warranty: Forever.

Money-Back guarantee: 6 Months after Purchase.

Manufacturer: The Quick Extender Pro Corporation

Official Website: https://www.quickextenderpro.com/

Expected Growth: Min: Adds 1.2 inches in length when used 8 hours each day after about 5 months. Minimal girth increase of 0.5 inches reported.

#6. The Male Edge Extender

This is a Type 2 Medical Device extender model made by scientists in Denmark.

Unlike the Quick Extender Pro and X4 Labs Extender, it does not use a clamp part to hold the tip of the penis.

Regardless, sizing is still present thanks to its medical quad-strap system. Not only that, but it is also fairly simpler to attach to your pelvis.

Based on other verified Male Edge reviews, some have reported average user-satisfaction.


  • Accommodates a wide range of penis sizes. It can adjust to any penis girth by adjusting the position of the two rods.

  • Fairly good in the qualities of wearability and comfort. Of the many clinical extenders, the Male Edge shows that it can compete with the other ones on the market. It has comfort features that the other extender brands lack. It works by distributing the stretching force along whole length of the penis, as recommended by urologists.

  • Scientifically Proven Materials: It is made out of various ABS plastics. Users won't feel any pelvic tension when wearing the Male Edge. This extender is also safe for men who are sensitive to harmful materials and chemicals.


  • Very Expensive Price: $149 (MaleEdge Basic) to $199.99 (MaleEdge Pro)

  • It lacks the inspirational design provided by the other extenders in this review, especially because it's design is basic and ordinary.

  • Lacks Cushioning Foam - the consequence of this is that, it may be too rough on the skin of the penis.

Warranty: A few months.

Double Money-Back guarantee: A few months after purchase.

Manufacturer: Official MaleEdge Store

Official Website: https://maleedge.com/

Expected Growth: Min: Adds 0.55 inches in length when used 6 hours each day after about 4 months. Minimal girth increase of 0.32 inches, clinically documented.
