As of December 2008, one of the controls failed. When plugging the blanket into the wall, one of the controls shows "88" continuously. It does not want to reset.Read other reviews. Other people have similar problems. The blanket lasts only 1 year. I will buy a different brand this time.--------------------------------------------------I wrote the following review during October 2008:--------------------------------------------------I purchased this in Fall 2007 (Amazon was the seller). It still works great. The blanket is a soft fleece. I have a sheet underneath it and a blanket on top of it. The preheat function is wonderful (heats the bed and then reverts to your normal setting). I only use L or 2 or 3 throughout the cold months.There are no clicking sounds when it turns on/off to regulate heat, and there are no "shocks" when it turns on/off.The controls works well. I have a king size (so dual controls). They are dimly lit, so you can see them in the dark, but they are not too bright. And the blanket shuts-off in 10 hours (if I remember right). So, if I forget to turn it off, it turns-off automatically.I would purchase this item again, if I needed it.
