Got this for my 78 year old mom.  She is always cold in her living room, even when using a portable heater. I was worried about her keeping a heater plugged in and tripping over it. This blanket solved all the issues. It has dual controls. One for each side of the queen blanket. She only needs to turn one on. It has automatic shut off and many levels of heat. She loves it! It is a little pricey.
