Real Customer Reviews

I'm finding it hard to put into words my amazement with this product. I bought mine as an experiment, expecting nothing, and wanting to prove there's no way it works. I didn't get the increases a lot of other people did but I also only averaged about 3 hours a day. The results are still noticeable and undeniable. The wife also notices the difference and loves the gains. Worth every dollar spent!

I like sizegenetics in general, but it is not so simple to wear it, like is demonstrated in the video, on hard dildo.I have average size of penis (around 7 inch), but is dificuld to keep it on, once penis loose all blood and become flacid, that it does eventualy, and everything that is one, get loose, so I have to constantly fix the traction, to keep the presure.Progress is much more slower, like it is avertised, but maybe depends on the person.

The product the company offers works great for what it's intended for, takes some time getting used to but with the friendly how to video cuts the time in half. Be consistent, that is key to getting the desired results; if it seems like it's not working, keep at it, the wait is worth it. Follow instructions carefully for best results. Good luck!

I have been dealing with Peyronie's disease for several years. I didn't want to go for surgery, I thought there must be another solution. I started looking and that's how I ended up with Sizegenetics. I was very skeptical at first about what they promised, regarding the increase in size but also about Peyronie's disease. However, I said I had to try, I had nothing to lose. The results were exceptional, from all points of view. The biggest problem was the psychological one, Peyronie's disease brings with it ED but also a decrease in size due to the decrease in the volume of blood circulating. Everything has changed since the beginning. I haven't treated Peyronie's yet but things have improved. And as for the increase in size, there is no doubt, it works. Just like it works in the case of ED.

Great product
It worked great for me!If you have strog will and commitment to go through the plan,I will highly recommended Sizegenetics!

Ollie

Excellent quality
The design and engineering of this product is excellent. I have been using it for more than one year now, and I find the silicone tube noose fit me best. One tip would be to clean the tube every day with hot water and dishwasher soap, this will result in higher friction (more grip) which again makes it more comfortable. Before I did this the tube tended to slip slightly and that was uncomfortable.

The buying and shipping experience was…
The buying and shipping experience was streamlined. The item arrived on time an was shown on site. Customer service was prompt to respond every time I have contacted them.
 The results from using the stretcher are real but you have to put in the time. I have gained 1.5 cm over a little over a year period. I am a builder and can’t wear it during my working hours so I am putting in less daily time than ideal. The result are just slower than using the recommended amount.

Donald Cramer

Impressed with the results!
 I was skeptical at first, but after using SizeGenetics consistently, I'm genuinely impressed with the results! Not only did I notice some extra inches, but the device is also comfortable once you get the hang of it. The quality feels premium, and it's backed by real science, which gave me more confidence in the process. I'm thrilled with my progress and would recommend it to anyone looking for a safe, effective way to enhance size. It really works!

John Mike

Jason Greenlee

Really Satisfied with the product
I have been using SizeGenetics for a while to help with my curved "friend", and it's really working. The device applies gentle tension to straighten things out over time, and it's surprisingly comfortable. I've seen a noticeable improvement and feel way more confident. Definitely worth a try if you're dealing with the same issue.

This product works exactly as advertised
I have used Sizegenetics for about 6 months. The product works great. I have had to replace the silicone tube about once per month. Consistent use has given me consistent results

Products work as advertised!
I've ordered several products from Sizegenetics and they work exactly as advertised. The ordering process is simple and delivery is relatively quick and discreet. I couldn't be happier with the products I've ordered (and my partners are quite satisfied, too).

Quality Product and Good Support
 I was skeptical at first, but the SizeGenetics traction device has exceed my expectations. It's sturdy, and the comfort pads really make a difference during long sessions. I also had a few questions, and customer service was excellent.

Alex

Good product that actually works. I actually gained results within the first 2 weeks of using. The reason I gave 4 stars is because the product I was sent is a little stiff on the screws. I need to use a little force to expand them

Nick

Time+Effort+Discipline = Big results for my Manhood
Works great but it requires time, patience and endurance, do not expect results in less than a month. I have been using it for more than a year since April 2023 now in combination with a pump and those 2 has done wonders. It was hard to vet a grasp of it at the beginning and really weird because Hey you are venturing into the unknown... Do not forget to get your diet and sleep on point and get a lot of protein and minerals intake to help it grow stronger. I wish I had done this earlier because it give you a truly great ROI on your sex life and it is a mental boost as well. If you can grow your manhood what else can you do? Most people are making funny jokes about penis length but are not doing anything to improve it nor do they think it is possible and you get laughed at for doing so. They are those that do and make it happen and other who watch on the sidelines!

The Most Comfortable Extender In The World.

1) Enlargement

Tests show an average increase in erect length of 28%, and 19% in girth after 4-6 months of treatment. The treatment uses your body’s natural response to traction, and the achieved results are permanent. The principle is called “Cytokinesis” – in layman’s terms, cell multiplication. The creation of new cells sometimes does not happen in the direction of the traction, which is why you also increase girth.

2) Straightening

The traction therapy straightens your manhood. Few men have a 100% straight member, and for many, it is merely a cosmetic issue. Some have a more severe curve – also called Peyronie’s Disease – which can cause problems during intimacy. The straightening of course also adds to the length.

3) Stronger Erections

The SizeGenetics traction device not only increases penile size but also increases blood flow by as much as 120%, making it easier to achieve and maintain an erection. Also, 12-18 hours after SizeGenetics penile traction therapy, you still have increased blood flow, amplifying your arousal level.

Frequently Asked Questions

How does SizeGenetics™ work?

The SizeGenetics™ device is based on age-old traction techniques that have been practiced for thousands of years to enlarge body parts. It works by applying a constant traction force along the shaft of your member to make it longer, thicker and harder. If you stretch a balloon, it becomes more supple and can hold more air. The same principle applies with your member.

Is the SizeGenetics™ device safe? What medical backing does it have?

SizeGenetics™ is a certified US medical type 1 device. Doctors have also endorsed our powerful traction device. So you can have total peace of mind that SizeGenetics™ is both medically backed and completely safe to use.

Are the results permanent?

The SizeGenetics™ system uses a constant traction force to increase the number of tissue cells within the member. This is called citokineses. This traction force multiplies the cells within the member permanently, which means any enlargement you see will be permanent.

How long will it take to see results?

Although results will vary depending on the individual and how long you wear your SizeGenetics™ device, many of our thousands of satisfied customers have seen results in just a few weeks!

How long per day do I have to wear the SizeGenetics™ device?

We recommend that you wear your SizeGenetics™ device for between 3-6 hours per day. You may want to start wearing the device for just a few hours per day before building up to 6 hours, to allow your member time to get used to being stretched. Every hour counts as the same, so wearing your device for 6 hours per day for 10 days will give you the same result as wearing it for 3 hours per day for 20 days.

Will it increase my flaccid length as well as my erect length?

Yes, you will see an increase in both your flaccid and erect member length when you use the SizeGenetics extender.

Will I keep getting results if I keep wearing SizeGenetics™?

Yes! As long as you continue wearing your SizeGenetics™ device you’ll continue to see results.

If I stop using SizeGenetics™, will my member go back to its original size?

No! Because the SizeGenetics™ device increases the number of cells within the member permanently, the results you get with SizeGenetics™ are also permanent.
