Rated 4.3 out of 5 by 43 reviewers.
Rated 2.0 out of 5.0 by Big disappointment It was nice while it worked but it no longer works. We believe it is the thermostat but cannot get the program instructions. We are disappointed because it truly was nice to walk on warm floors in the dead of winter. The manufacturer needs to back its products. December 15, 2014
Rated 5.0 out of 5.0 by Would recommend the purchase Received the product quickly. Installation was very easy, although purchase of the Loudmouth alarm was necessary. Product is durable and the tilers had no problem working with the product. Electrician had worked with product previously and highly recommends it. Once installed, it heats up quickly, programmable thermostat was easy to se up as well. Absolutely love walking onto warm kitchen floors. Planning on replacing tiles in the bathrooms and using mats to warm those floors as well. One note. Wires can be removed from mesh to wrap around corners and odd angles. One does not need to purchase several mats to accomplish this task, just some creative thinking. December 4, 2012
Rated 5.0 out of 5.0 by Easy to use! Instructions are clear step-by-step. Screen has good contrast. Super easy to just set and let the controller do all the work! April 7, 2015
Rated 5.0 out of 5.0 by Good product We liked that the Sunstat comes with ground fault protection. It's easy to program and then just leave it alone. It's nice to have a clock in the bathroom. I recommend having an electrician install it. November 11, 2014
Rated 1.0 out of 5.0 by Stopped working after just 6 months Installation and setup was really easy. Unfortunately, the unit stopped working reliably after just 4 months and quit altogether after just 6 months. The manufacturer is making me jump through hoops to get a replacement. So far, I have not gotten them to agree to replace it. February 7, 2014
Rated 1.0 out of 5.0 by Expensive for the quality and poor performance. Noisy relay clicks on and off with heating cycle. Maddeningly slow when set temperature is only one or two degrees above current temperature. In the latter case, will not heat continually until it reaches temperature, it will leisurely cycle on and off. You have to raise the temperature higher in order for it to heat continuously with the end result being that you will likely overshoot your intended target. Customer service offered no solution other than to buy their more expensive model. In between seasons, if you shut off your breaker, you will lose your program. February 9, 2015
Rated 1.0 out of 5.0 by Disaster This product worked great the ONE day it decided to work. It now only works if you directly connect the mat directly to the power panel. If it's connected to the device - sorry. Have tried for years now to get help with the product but the support is nonexistent. So for four years now I've had a pretty electronic box on my wall that does nothing. All testing suggests there is no damage to the mat or unit. Just a terrible product and waste of money.

Rated 5.0 out of 5.0 by Great and working so far. This thermostat is working far. We lost our original thermostat last just stopped heating with no error codes. Then we installed another, which worked for a month and did the same thing, stopped heating, no error codes. The GFI feature seemed not to work on that thermostat. So, this Sunstat thermostat is working fine and the GFI feature is working fine. It also seems that our room, a sun porch, is heating much better. I don't know if the old thermostats were not work properly or if the Sunstat is more superior or a combination, but we are pleased so far. No problems installing other than the plastic cover was difficult to get off, I thought I was going to break it. It eventually came off though. January 31, 2013
