I just wanted to comment that I saw this for the first tie in a late night TV ad last Wednesday. I hurt my lower back, and all the muscles of my lower body stiffened up on Thursday. It takes two months to get n to see my doctor. So I ordered it on Friday from Amazon and got it on Saturday. I have been using it three times a day every day, and it really seems to be working. I can walk now. The most pain I have is an area on one side of my lower back.
I am pretty skeptical about TV inventions. This seems to have some real merit to it, and I will keep using it. I just wanted to let you know.
Bottom Line: Yes, I would recommend this to a friend
