Question: I bought this heating pad to replace one I'd had for many years that stopped working. I looked at all the big brands offered here on Amazon and was not happy to read that Sunbeam and some of the brands I'm familiar with had bad reviews (caught on fire, stopped working after a short time) so I kept looking. I came across this heating pad and decided to order it. I've used it twice now, and I'm very pleased with the larger size and the soft cover on it. It heats up quickly (there are three heat settings), and has an auto-off after two hours. I also like the longer cord length, since there's not always an outlet handy when I need to use it. I will report back if I have any problems with this pad, but for now I am very happy with the quality, price and performance.

Answer:
positive
