The pad really does a terrific job of heating up and holding set temperatures; however, I'm not thrilled with the fact that I'm not supposed to lean back into the pad. I don't understand this stipulation at all although I am abiding by it. When the pad is in use, I'm either sitting up (in a forward leaning position) or lying down with it on top of my back. So far so good and I would recommend this product to anyone experiencing slight tenderness in their back or to help alleviate simple back soreness.
