UTK Heating Pad for Back Pain Relief

I have chronic illnesses and this is one of my go-to comfort items. I mainly use it for pain, but it helps with relaxation too. It is a far infrared heating pad that goes deeper than a normal heating pad (I think it is because of the Jade stones? I’m not totally sure how that works though). It also has settings you can set up so it will auto remember the temperature and for how long you want it to go for before shutting off. I’ve used mine for years and am so pleased with it.
