And excessively hot to the touch! Couldn't shut off with the on off button. Had to unplug it. My husband bought me this beautiful comfortable king size dark brown electric blanket for Christmas of 17. Noticed about the 4th time using it it wasnt heating up correctly. Then tonight I turned it on preheat to return in about 5 minutes only to find the blanket not warm and the control panel insanely hot with a solid blacked out screen! 
He paid way too much for this to have these types of issues for only have been used a handful of times.  Wish I could recommend but not under these conditions.
