Very good. I have bought it in other sizes for the face. It is perfect!! It works on cellulite. I read that it doesn't stick well to the skin... It sticks just fine... you're not using it properly.. it needs some oily product to do a good job and glide, not on dry skin or with a little cream. That way it doesn't do anything.

It does its job just fine, without fires and alcohol. You can put them yourself in certain points of the back where the hand reaches.
