I just purchased this yesterday. I have lower back and hip problems. Arthritis they say. I am hoping this machine will help. I have used it twice now and what I can say is, it doesn't hurt. It actually feels kind of nice once you get passed the being nervous part. I think it will help loosen up my stiff joints in time. Its a keeper!
Two or three years ago I bought the larger vibration platform and I like it a lot, but I was very interested in the waver also, So, I bought it a few months ago and put it in my bedroom. I love being able to work out or just stand on it before going to bed. It really relaxes me.
