Bests & Worsts Reviews from Amazon

I purchased this product and it worked for three days then completely stopped. The seller replaced it and I re-installed it on my bed. The second one worked for a little over a week before it over heated and burned a hole in itself. There was a heavy fried electrical smell in my room. Now, apparently I don’t have the option to return it for a refund. This product is faulty and possibly dangerous, I would not recommend buying it.
