Doesn't get hot enough, shuts off after 15 min on high, and massage mechanism creates more pain
I was so excited for this product to arrive. I like the size, shape, and magnetic closure. Unfortunately, it does not get hot enough. The high setting automatically shuts off after about 10 minutes. The massage mechanism makes me feel like I'm sitting up against protruding size D batteries. It is uncomfortable, and I swear I have new knots in my muscles because of the protruding massage mechanism.  If the manufacturer made the mechanism the size and shape of a 9-volt battery, then I would buy the pad just for the massage feature.
