The X4 Extender is by far the best product on the market when it comes to fix a penile curvature. Not only was the customer service impeccable, the shipping ultra fast, but the device itself works miracles. I don’t want to sound cheesy, but I owe a lot to you guys. Thank you so much for being there to answer my questions and providing a product that can actually help men born with unfair disadvantages.

Had a little extra money last summer so I allowed myself to buy the X4 stretcher. What started out as an impulse purchase has turned into a positive long-term investment. My peyronies disease goes back half the way. Guys! Thank you so much for this opportunity

I've been using the X4 Labs device for over 4 month now. My penis was curved to the left and was hurting a little bit. But with the help of X4 Labs i was able to fight these pain and the curvature goes back.

I have been using the X4 for one month. It has improved my Peyronies Disease very much and my penis seems thicker. I use it as much as I can. I use it for an hour at a time, after it is off for 15 to 30 minuts I can put it back on for another hour.
