I did a lot of research before letting my daughter order this, mainly because I have a drawer full of gadgets that did not work. Pillows, creams, a TENS unit I used twice. I even saw a cheaper lookalike on Amazon and almost fell for it. I was skeptical that something like this would work on arthritis I have had for 8 years. Was I ever wrong. By the second week the morning stiffness was easing, and last Sunday I sat through the whole 9 o'clock service without shifting once. It is the first thing from the internet that did what it said. On damp days I do 2 sessions instead of 1. I wish I had found it before the injections.
