Love this blanket!  It's the perfect size for when I'm sitting on the couch (I got the "full").  It's super soft and cuddly and the temp is perfect.  My husband always runs hot, so it's nice to be able to throw a heated blanket over me... and then we are BOTH happy.  

The variable control is easy to use, and it goes up to 20.  I start it out at 20, and then have to back it down to 5-10... as it gets pretty warm.  It's wonderful!
