The thermostat seem to be fine but the app sucks. I purchased this so I could use my phone to adjust as needed but in the 3 weeks I have had it there have been several times where I couldn't use the app to connect or have had to force stop the app to connect.
So far so good. Easy to install and has been working great ever since. Love being able to monitor and change the temp from where ever I am. Will likely get one to replace the upstairs thermostat as well.
Attractive Display, Adequate App. Works great. I would rate this a full 5-stars if the app were a little more functional and the display offered more details like the weather forecast (vs. just displaying outside temp and humidity). I like the interface of the Nest better, but our new home did not have the necessary wiring. But, as a replacement, this thermostat and app are adequate.
