If I could give zero stars I would, but at least one. Something that doesn't work shouldn't get any stars. I have a second power cord/switch and neither the first nor second purchase stays on to heat the mats. The mats I have match the manufacturer's performance specifications well. The power cords are immediately unplugged instead of being restarted from time to time. I have reduced the number of mats on the track but to no avail. It was nothing short of disappointment and madness. This hardware doesn't come cheap and you should think it should work as advertised. I'll try calling the manufacturer and see what happens. My suspicion is probably not good.
