We live in a old New England house with an un-heated upstairs bedroom; we depend on our electric blanket to keep us warm.  Our previous Sunbeam was a different fabric, and my wife hated it because it was so difficult to get it smooth and square when she made the bed.  Also, like most of the newer models, it would not preheat and never seemed to get really warm; we needed two blankets on top of the electric blanket to stay warm in our cold room.  This new Quilted Fleece model feels more like a regular blanket and makes up just fine.  Still marginal preheating capability, but it warms up immediately when you get under the blanket, and is noticeably warmer in operation than our previous blanket.
