Warmest, luxurious electric blanket I've ever had.  Great quality and heats up really fast.  It's fall time and my husband runs warm, so he put his side on level 2 which he loves, and I set mine at level 5 which was already pretty warm.  It goes up to level 10...will be increasing for winter.
There's a timer to turn it off automatically, but we unplug in the morning by habit.  Surprisingly, we both slept better with this blanket.  The sherpa makes it so soft, and provides a warm layer without being on as well.  Easy set up, just read the brief instructions.  We purchased the king size.  I'm getting two more in different sizes.
