Size Genetics has been moved up to number one in our reviews because they have a new design for the piece that attaches to the penis. This has no bad meaning for the X4 Labs which is still a great penis extender but even though it is slightly cheaper than the Size Genetics the new design means it is second best.
The bit that attaches to the penis has to be comfortable and not cut off circulation. Of course this has to be done while still mainting a good grip to stretch the penis and it is always hard to find the middle ground. Size Genetics has done just that though and this works for everyone as there are so many ways to attach it.
Up until the new design Size Genetics and X4 Labs were on equal terms to do with how effective they were. The only difference was the X4 Labs was slightly cheaper. Of course that hasn’t changed but the new design means you will get faster gains and even bigger gains making it well worth the money.
