I have this electric blanket now almost four years. And I have consistently lying in bed :-) under the fitted sheet and a mattress protector and still makes them very fast very warm. The thick cable I turned down, the cable runs under the bed along in a multiple plug. Since I always have the setting to "full power", I then draw just the plug if it gets too warm. I would buy the ceiling at any time (the next time then only a little longer).
