This is an excellent product.
I live in an old house in Cincinnati, Ohio, U.S., and it's not exactly cheap to heat my house in the wintertime. With this heated mattress pad, I'm saving almost $70 a month on heating bills, which means that this thing pays for itself in about two months. I can turn my heat down at night, turn on the bed (I like it a little warmer than the preheat setting) and get into a nice warm bed at night. Only problem-- it's really hard to get out of bed in the morning!
This particular mattress pad also has a very nice, soft quilted top. It's the second heated mattress pad I've owned, and the previous one didn't have a quilted top-- you could feel the wires a bit. This one is much more padded and comfortable.
I also like that it has a 10 hour automatic switch off-- no need to worry that I leave it on while out of town, etc.
Excellent product I would recommend to anyone, absolutely worth the money, and a real relationship saver for couples... Read more

We have gone through 2 of these mattress covers within the span of one season. Initially they work fine, then they seem to develop "cold spots". Eventually, they cease to function at all. Also, one of the digital controls started reading erratically, jumping from level to level. Too bad, as they are wonderfully comfortable. One would expect them to be a bit more reliable. I'd try a different brand.

This is an expensive product. We live at the ocean so we don't need a lot of heat, just a few nights a year. Last night my side was cold and the guage said 88, whatever that means. We couldn't cut it off or on! My husband's side is fine. I've had three other electric mattress pads over the years and this is the most expensive and lasted the least amount of time. There's no way of fixing them either. I'll buy another but not Sunbeam. They seem to not have the quality of other brands.
