I have one in my house and I love, love, love it.

I find that our house temperature is overall better regulated and best of all, REALLY easy to adjust. No multiple buttons and switches to deal with when changing the temp. As an added bonus, our daughter is so into seeing the green leaf appear, that she will lower the temperature when she walks by. It's totally got her conserving energy.

Hi there, very late coming in on this post, but with the Nest Thermostat, can you regulate different rooms as different temperatures? Many thanks, Denise

We just bought one last week. Have not yet installed. My husband is so excited. Was his idea.

@drennden It just replaces your thermostat; it doesn't magically break your furnace system up into more zones. :))
