I got this throw blanket for my fiance about a month ago because her old one stopped working. We live in Texas, so we don't really see cold weather outside, but our house tends to run on the cold side, and when I had got it home, not 20 minutes later and she had it was plugged in, and we were both under it. We love the fact you can turn up and down the heat, and it has a timer on it, so it doesn't just run all night because yes, we do sleep with it. I highly recommend this blanket!
