I found this out first hand on Dec. 30, 2011. I wont mention the manufacturers name but the blanket was less than 3 weeks old and started a fire on the bed when nobody was home. The blanket was plugged in but the controller was not turned on. I knew there was some problems years ago with electric blankets/ heating pads but never gave it a thought when I told my wife to buy the blanket, I was just tired of fighting over the thermostat. Anyways, I have plenty of time to think about while we are staying in an apartment for the next 5 month. Be safe guy's !
