Query: a good heating pad - with no automatic shut off

This heating pad does what a heating pad is supposed to do. However, I was really surprised that it doesn't have automatic shut off! i have a really similar one (I thought I was buying an identical one) that does shut off. This is especially disappointing because my husband likes to have it on his back in bed, and he wakes up covered in sweat (I realize the directions probably say not to sleep with it on, but surely lots of people do this). I would recommend spending a few dollars more for one with automatic shut off.
