Work as a heat pad
The only reason I purchase this is for its large size as a heat pad. I did not test its claim for Pain relief. It works as a heat pad, but I do not like:<br />USB cable is poor quality. I total purchased 3 of these. 2 of those the USB cable broke in less than 2 months of nightly use. The 3rd one work so far so good for 2 months but winter is over and I already put it away. The problem seem limited to the USB cable. I replaced the USB cable with a high quality one and it has been working.
