I have to say this is SO much better than the two other [words=https://shop.mattersofsize.com/products/sizegenetics-penis-extender]extenders[/words] I bought. I have size gentics and fastsize ones and have had them for a couiple of years. I wore them off and on but mostly off. They hurt like hell and wear marks on my skin if I wear them for any length of time. Thanks to Stevie7inch for bringing up this product because I am impressed and happy. So just to let you guys know so far so good. I'll keep you guys posted!!
