Best adhearing heat pad I have ever used!
This adhesive pad is far better than Theracare pads.  Theracare pads for the back are not adhesive, and are kept on using a wrap around belt with velcro, which I really hate.  The adhesive pads are far easier and don't move or get in the way with clothing.  The heat is a low/warm level, but really effective in easing back pain, and the best thing is it really does last 16 hours.  I used two of these pads so far, and they really reduced my back pain when it was bad.  My only issue is that these are expensive, and I wish they were lower in price.
