I hate to be the lone dissenter, but I really, really, REALLY dislike this device. (I would say I hate it, but I don't want to use the "H" word twice in the same sentence. But I hate it.) It feels cheap and when I use it on my face, the brush slows to a crawl and then stops. I have seen absolutely no difference whatsoever--probably because THE BRUSH STOPS. I use the dermabrasion crystals in the shower with my fingers and the product is ok--but no great shakes. There are reviews online that say it's the same as a popular drugstore brand. If that's true, it's not even worth the $20 cost of that brush. SO disappointed.
