"I noticed that other penis extender sellers sell pills with their extenders. I called the toll free line, and a guy called Mike told me that the pills don't work. I didn't believe him until I made my own research and found out what theses pills are made of.testosterone boosters! Of course they don't work!"
Noel, Arizona
I was using a similar device that utilized the rubber tube/noose. The idea was the same, but it was so painful that I couldn't wear it for more than 45 minutes a day... I have since purchase the X4 upgrade and have been able to wear my extender from 5 to 9 hours a day without any discomfort.
Phil Belmont. Vermont USA
I've been using this extender for sometime now. I use it every other day and so far after 1 year, I have gained 2.3 inches in length. I've also noticed a significant growth in my girth. This device is so much more comfortable then the one I had before (jes-extender).
Mark Rose, Vancouver Canada
I spent so much money on cheap garbage to enlarge my penis, and was very hesitant about buying this. All I can say guys, is you get what you pay for.
One happy man
My wife didn't like the fact I was using this, I didn't listen to her and kept using it. She stopped nagging when she felt the results.
