Had a queen size blanket, and like many other reviewers here, the blanket worked great but now barely heats up or not at all.   With so many complaints saying the same thing I would think that Sunbeam would acknowledge this problem and discontinue sales until it is fixed or tell the customers this blanket will only operate for a year and that is it.
Two of the three Sunbeam electric blankets I have purchased did not last more than two years. There will not be a fourth.
