The thermostat itself is fine. The app itself is fine but it would be so much easier if configuration and programming could be done also on a PC like some other Honeywell thermostats.
I had an old fashioned style so this is a vast improvement. Love the fact that I can use my smart phone to control the unit and the operating instructions are easy to understand.
Works great. However, One occasion had it go offline. Apparently, Honeywell servers went offline. When adjusting thermostat at the wall, there are delays with the app updating to the new thermostat setting. Other than the above, the thermostat works great.
