I was curious, so I asked my wife to get me one for Christmas. So far this thing far exceeded my expectations. It pretty much melts away tightness and soreness, even bringing out things that you didn't know you had. I've also used it a couple of times to massage out injection sites after injection, and although I don't get a lot of pip, I think it may help with that. Does anyone else have one of these or have been curious about them?
