As advertised, helped to regulate the temperature in our kid's room that tended to be a bit colder than the rest of the house (turns out about 3 degrees cooler). The Cync app was a bit confusing for the set up but found a couple of YouTube videos that helped. Unit was much smaller than I thought, a little larger than a quarter. Something to note is that you'll need to set the sensor as the "main" sensor for your Cync to regulate temperature based on it's readings, which will then ignore temperatures read at the main unit. I'd love it if there were an option to work towards an average temperature.

I have had no complaints from these sensors and they help me better understand how each floor's temperature changes from hour to hour.
