For the past year, I've been in the process of regrowing my foreskin. I've been seeing great progress, and my bf loves the feel.

I looked into a bunch of different companies before going with SR and have been very happy with my decision. I started out with a plastic version of their device and liked it so much that I got a stainless steel model with an extra weight attached. Can't recommend them enough!
