Thank you…I had a heating pad and it fell apart on me, after a year and a half using it every day. I was heart-broken because I have a very bad back…it hurts all day… and now I had knee surgery. I found your site [] by accident and now I have enough money together to get three of what I really need. I feel so blessed that I can get these now. Thank you so much …My grand kids will get some for Christmas for their tummy aches. They love to use mine when they’re not feeling well … bless you.
