Query: Don't Waste Your $$

I was really happy with the design of the pad when I first purchased it. It had no sharp plastic corners to poke me and was big enough to cover my whole back. My pad lasted a little longer than the other reviewers' pads... several months. It quit working, so thinking there may be a bad fuse, I took the controller apart. Yep, a bad fuse. Only problem? It's saudered directly to the board. I can't just pop it out and replace it. Based on this and the other reviews, I definitely will not buy another SoftHeat heating pad.
