These are awesome! Given the price of oil right now and the cost of heating our home, I bought one for each bed in the house and it’s reduced the heating bill this month by almost half and it’s much colder outside! 
A great solution to high energy bills.

I had to reduce my 5 star review to three. After using these blankets almost nightly for a few months now, one of the blankets has malfunctioned and the wires close to the plug looks to have melted exposing the wires on that blanket. I’m disappointed. The other four blankets have not had this issue yet.
