Many people have submitted reviews complaining about the x4 labs penis extender calling it a scam and questioning if the extender does actually work. As a long time user i back their product completely. I was extremely self conscious about my size in the bedroom and thanks to x4 labs i was able to gain a total of 3 inches over the first few months. So do dont doubt if penis extenders do actually work. They are not a scam and are safe. The reviews i read at <a href="www.shallwemate.com">Shallwemate.com</a> were really useful so thought i would share.
