I was a little disappointed after using it. But again the user experience varies from person to person whats comfortable for me may not be the same for you. Quality wise this product is quite good.
I bought this about a month or two ago It's very powerful and takes some time to get used to. I think I would prefer the other one with the rounded head on it. Sometimes I feel as if there's not enough direct pressure all the way around .. I have a way cheaper version (of course not the same , but same idea) and I always seem to reach back for that off brand one. Either way , once you figure it out it's great.. for me it just is taking a little bit of time to figure out.. great quality and battery life.
