I needed a small area heated to melt snow that comes off the roof by our front door. The 3x5 mat was just right. The website write-up was accurate, ie I got just what I expected. It was easy to install (wiring can be the trickiest part, but that's not a WarmlyYours issue -- I wired it to an inside manual switch). All in all, it was what I needed, easy to install, one or two phone discussions were helpful, and it works great.
