Great Fit, No Discomfort

The biggest concern I had was comfort, but I was pleased to find that it was easy to adjust. After fine-tuning the fit, I could wear it without any discomfort for hours at a time. It became part of my routine, and I started seeing great results after a few months.

Comfortable and straight forward.

I have tried using a traction device for PE in the past and discontinued using it because it was uncomfortable. I got this one because all the reviews stated it was comfortable and it lived up to what everyone was saying. It is straight forward and the with good pressure. I feel this device will help me reach my PE goals.

Surprisingly Comfortable!

I expected it to be uncomfortable, especially after hearing so many different opinions. However, to my surprise, it was comfortable enough to wear for extended periods. It didn’t disrupt my daily routine, and after some time, I started seeing small but significant changes.

High Quality Device, Great Support

I’ve been using SizeGenetics consistently alongside a structured training approach, and the quality of the device has really stood out. It’s well-built, comfortable for long sessions, and easy to adjust as progress continues. In 4 weeks as part of ny optimal protocol I've already gone from 6.2 to 7.2 inches along my journey and just boyght so ewtendors to help me get to my goal fo 12 inches length!

Their customer support has also been solid—fast shipping and responsive communication. I’m committed to a long-term transformation, and I’m confident SizeGenetics will remain an essential part of that journey.

Highly recommended for anyone serious about progress.

Gradual but Noticeable Changes

At first, I wasn't sure it would make a difference. But as I wore it regularly, I noticed a gradual transformation. The changes weren't dramatic overnight, but over time, the results were exactly what I was hoping for. I feel much more confident now.

Big Confidence Boost

Used it for two months, I never imagined a device like this could make such a difference. It’s more than physical—it’s been a boost in how I feel about myself.

NOT Impressed with the build of the product…

WAS - "Impressed with the build of the product and particularly customer support. Looking forward to seeing results with it. Been comfortable to use so far."

However, 2 weeks in the device has had its second failure and they won't assist. Replacement parts are stupidly expensive and make me think this is their business model. Strongly recommend against buying this product.

These guys are simply the best

These guys are simply the best. When I first bought my size genetics value edition, and it had an issue of a loosened screw, which led to the removal of the spring, in the hexagonal piston, I received a video, instructing me on how to properly replace the spring. My same value edition tool, recently stopped turning at the hexagonal piston and hand screws, on both sides, and got new parts ordered for me to my surprise.

1st Month for those on the fence

It's been a month and I am pleased with the results have been amazing, My routine only varies on the days that I work I try to do it for at least 6hrs and my days off at least 10hrs, for those that have peryones(curvature) the first thing you will notice is increase in girth that's probably due to the lack of muscle tissue that has not grown typically on the side where it curves, you'll notice how the trunk or shaft of your johnson is the first thing that gets thick and strong which will already prove to work wonders when you get to action time, so after 1 month of use it seems like my girth has increased significantly and my length probably has close to half inch, but the most glorious aspect of all of this is that my wife cannot stop screaming when I'm inside of her(I swear this is 100 percent truth, for those that believe in God you all know swearing is a big deal), I also made her cry (lol ) which was a bit confusing at first cause I thought she was going through pain but she kept kissing me and told me afterwards that those were tears of joy and that she is amazed of how strong she feels me down there.My main purpose with this review is to address those who are on the fence about getting this device specially those with Peryones:
- The size, girth and strength of your johnson is in a crippled state because one side(typically the side where your johnson is curved towards) of it has not developed muscle tissue to be in its optimal state, hence it means that because of it you have a reduced girth and and length just by having Peryones WHICH IS NOT HOW IT WAS MEANT TO BE, believe me is the equivalent of having a muscle imbalance, so far this is the best way to fix that muscular imbalance on your johnson.
- It might sting a little bit: For those that stretch regularly or do yoga you will understand how muscle tears work , in my case with Peryones it stings on the side where the tissue has not grown or developed and I have to take deep breaths or change my breathing patterns according to the gravity of the sting(it literallyfeelsas if needles are getting pulled out of the side where you have the Peryones), if the stings get too overwhelming I remove the device and I let it rest until the stinging stops to put it back on and complete my hrs , if you do yoga or stretch regularly you won't have a problem reading when to take it off and putting it back on, but just remember because you have peryones your experience will not be pain free ,Everytime you put on the device probably around the 3rd or 4th hr of wearing the device it will literally feel as if needles are being pulled out of the side where you have peryones, just be patient and breath accordingly cause it I'll be worth the effort. DO NOT HYPER EXTEND YOUR JOHNSON, GO SLOW WITH THE EXTENSION AND INCREASE LITTLE BY LITTLE.
- If you you feel uncomfortable telling your partner about the device just tell her the following in your own words(for those with Peryones):
Say you magically stumbled upon information that led you into deep research and you finally found out that you have an unnatural muscuĺar imbalance(which is not a lie) on your Johnson and that you are going to get it fixed with a device, say something that goes along those lines and she won't give you issues, in fact she'll love you more once she starts feeling you stronger, longer and girthier(typically after 1st month of use).
In closing: feel happy that you found a way to give your Johnson a workout thats effective and that can be worn anywhere without being detected, my curvature has not yet improved too significantly but my length and specially my girth has, I guess once the muscle tissue becomes more balanced that's when Mr Johnson is gonna start getting straighter, at least it feels that way so far. THE MOST IMPORTANT THING IS TO TRY TO GET AT LEAST 6 HRS A DAY AND DO NOT HYPER EXTEND which is how I have been doing it .
Trust me, you will not regret it .
