Our old blanket was 16 years old and not heating like it used to, so I needed to shop for a new one. This one was not exactly what I was looking for but the price was right. We have had probably four episodes where the blanket stopped heating and the controllers started flashing, but unplugging the blanket both at the wall and at the blanket and then plugging it back in, first the blanket and then the wall, restored normal operation. This has not happened every night but about once a week. Not sure yet if there is a problem, but when it is working it is wonderfully warm.
