Up until quite recently we had X4 Labs as our top extender, not so much because it was better than Size Genetics, they were about the same in every aspect but one, the X4 Labs is a little cheaper. This was the only reason it was number one but after some good redesigning by Size Genetics theirs is now the best penis extender out there.

They have changed the piece that attaches to the penis making it much more comfortable and easy to wear for long periods. That’s not to say that X4 isn’t comfortable, it’s just not in the same league now but for those who can’t afford the extra bit of money then X4 is still a very good extender.

Both of these penis extenders will work for you and both will give you a longer penis but the Size Genetics will do it a little faster and will give you an extra bit of length. The reason is that the longer you wear one of these the better it will work, more comfort means more time wearing instead of having to take breaks throughout.
