Rated 4.8 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Good Product We installed this as a back up sensor in case the original one under the tile fails. Well worth the price to keep from having to tear up tile if the first sensor fails. December 15, 2013
Rated 5.0 out of 5.0 by Ordered as a back up sensor I ordered this sensor to put in my heated kitchen floor as a future back up sensor to the one that comes with the thermostat. The price was good and it made it here in two days. Hope I never have to hook it up, but if my other sensor goes bad, I am resdy to fix it!! August 21, 2013
