This has only been used twice for my dad who had osteoarthritis in his back. In the two times he used it, it helped bring pain relief to his spine before he went into surgery so you can guarantee he had a good night's sleep in preparation. We bought this in 2014 @ $350. Still in excellent condition. This is guaranteed to bring relief to the back area using infrared technology. It's worked for dad so it'll surely work for anyone else.
