We loved the weight of the fabric and the warmth of it even without being turned on. It was about 2-4 inches too narrow for a Queen bed with 2 bodies sleeping under it. 
But the real deal breaker was that it didn't play well with the other bedclothes. There is something about this fabric that caused the sheets to go one way under it, and the bedspread to go the other way... way far away, and right off the bed.  It darn near caused a divorce, as my husband was sure I was pulling the covers off of him!  Returned it within a week. Too bad.  I was really excited to replace my old electric blanket with a much nicer one.
