This is a great electric blanket. It heats up great and has plenty of warmth through the night. You can not even feel the wires.  The best part is the blanket does not shift around.The only downside is the controlers . They do not have a back light, that makes it difficult to see the settings ,you can not tell if  it is on or off through the night. If the controlers were back lit, I would have given it 5  stars.
