Sizegenetics is an absolute scam. All of the websites with rave reviews about them are either made by them or get paid by them, don't believe the hype!
First, they are a Jes Extender re-badged and all they really do is boost the tension to DANGEROUS levels which cause pain and discomfort. They boast their products are clinically tested etc. they are using the Jes Extender credentials for their own dangerous products! Which with that tension have NEVER been tested. Their customer service just spews the same old canned responses which never help with the issue. Seriously, think about your *** getting pulled with almost 3kg of tension, how long would you be able to last? It's almost double what the original design of Jes Extender used, it's an absurd amount of tension to put on a *** for any length of time.
I wasted $395 on a product that can not be used effectively, not with the crazy amount of tension they say will give you "extreme results". They are full of it, don't believe their hype, their products are simply dangerous and have never been tested by anyone credible.
