This is a fantastic addition to my smart home. Setting up the hardware was a breeze. Although my old thermostat didn't have a C wire, I found an extra wire in the bundle. I connected it to the C wire slot on my furnace and linked it to the Ecobee, avoiding the need for the adapter.

The aesthetics are impressiveit's like a small piece of art on my wall. The large, readable numbers display the current temperature, and as you walk by, the screen changes to show the set temperature, just like in the product image.

An added bonus:
