It was a big issue on the forum on whether or not it worked, because there was no evidence to support some of the claims that were being made. Look up ROP and you'll find the threads that I'm talking about. I thought it worked well, I know that since I've stopped using it my orgasms aren't as "strong" and I don't shoot a whole lot when i do orgasm, but I think that maybe because I don't usually ejaculate if at all unless I have an accident during a session and don't squeeze my PC hard enough. Just my thoughts. If you want to buy one go ahead it's worth a shot.
