Biddeford Heated Mattress Pad, Full

I tried 2 Sunbeam models and returned both of them because they didn't work. This one works well. I really like the vertical display of the controller, makes it easy to see when lying in bed. The models that have a controller that lies flat are difficult to read when lying down. It's not a big deal, but this model doesn't really fit snugly to the corners of the mattress. It kind of just drapes over them.
