Beware, it gets very hot!

I purchased this to provide heat to damaged nerves in my arm resulting from shingles. Heat always feels so good on it and I wanted to be able to do household chores and things without trying to hold a heating pad in place. It works well, but beware if you have damaged nerves and cannot sense tempurature. I left it on for several hours and it burned the back of my arm. I actually had blisters! This was my fault, I learned a lesson... I guess I was surprised it could get that hot!
