A "firm" believer. lol. This was my first ever pump and I am most impressed. I will say you have to be shaven or well trimmed at the very least for you to get the suction that you're looking for. I tried using it with short pubes and it would not lock the seal. After shaving bald it work like a dream. I have paired this with pills and there is no doubt I have gained at least an inch or two. I was never small but just wanted more and this has proven an essential tool for those who want more to their meat.
