I've put this on my Christmas list this year. After reading TONS of reviews, I still have mixed feelings about it. I have super sensitive skin, but the knots and stress I have each day are hard to deal with. I'm almost always sore and seeing a chiropractor and massage therapist. Some reviews said that it takes a bit to get used to (because of the pain), but once you get used to it, it could put you to sleep because it's so relaxing. Does anyone have any experience and thoughts on this product? Thanks!
