Bests & Worsts Reviews from Amazon

UPDATE: I revised this to include some thoughts from the comments. UPDATE #2: I've added a few more thoughts in the comments. I now have a full size heater on my guest bed. It's been perfectly silent. I upgraded my review to 5 stars because of that. It's really hard to describe just how great this heated mattress pad is. You would think the "microplush" part wouldn't matter. But somehow, even through my 800 thread count sheets, I can feel the difference when I put this on my bed. Just having the pad on the bed is great even when it's not turned on. The heating coils are much finer (thinner) than typical heated pads so there aren't lumps and the heat is more uniform. The heat range seems quite nice. Of course, I live in Colorado and my wife likes to keep the window open. So we use a heavy down comforter with the heater. The pad itself wraps your mattress well. This will fit even the thickest Queen size mattress without danger of the pad sliding around at night. Now for the caveats. Yeah, I suggested there was only one but there are two important concerns: 1. The power inverter that converts the 110 volts AC coming out of your wall (which normal pads use directly) into lower voltage DC tends to make a high pitched whistle. I guess I didn't go to enough Rock concerts when I was younger because I am still sensitive to high frequency sounds. There are many nights where the whistle wakes me up. You have to unplug the unit to get it to stop. I usually through a pillow over the unit and that sometimes helps. It is high frequency, which means it's highly directional and easily blocked. 2. You cannot get replacement controllers. The manufacturer, PerfectFit / SoftHeat / Chattam & Wells, does not sell replacement controllers. After about two and a half years, my original controller died leaving me freezing while my wife was toasty. They did honor the five year warranty and sent an entire new pad with two controllers! Maybe #2 isn't really a caveat. They did a great job honoring the warranty and now I have a complete set of spare parts. But I'm still going to knock a star for #1. If you are sensitive to high frequency sounds, this may not be the pad for you. Otherwise, this heating pad really is great!
