It doesn't heat
I ordered this while we were without power for 24 hours recently. Not having a heating pad during a power outage was the biggest problem for me. Despite the bad reviews, I was willing to give it a chance. Per the instructions, I gave it plenty of time to heat up (more than an hour), AND I had it on my bare skin. It never got past the barely warm stage. Definitely nothing like a real heating pad. I'm returning it.
