COMFIER Heating Pad for Back Pain

the best part about this is that it is cordless, it’s easy to wear, easy to store, and easy to charge. but it is a heating pad and while it does feel great while it heats up, it doesn’t maintain the heat for very long. it goes through cycles of heating up and then cooling down considerably… and it gets cold and makes you wonder if it is malfunctioning but then it starts to heat up again. the cooling down and cold cycles last for several minutes and feels longer than the heating up cycle. For this reason i give it a “meh” score. if it maintained heat more evenly and didn't get so cool in between heat cycles, i’d give it more stars. The vibrations are just that, it just wiggles the belt on your body and it is loud. For me, i can take or leave the vibrations.. i don’t see that being a feature that would make me like this belt more than a regular heating pad without vibrations. the stars i did give it really come from being cordless and convenient… overall, it is just an okay product.
