I tried all of the big name thermostats that have tried to enter this market space. They will left me wanting. When I got the Nest e thermostat I was amazed from installation, tho setup, to daily case out operation there have been none better if you are in the market for a smart thermostat you can't go wrong with this one.
This product, so far, has been extremely easy to operate. The schedule can be adjusted at any time, from anywhere I happen to be at the time. This item was included with my security system, and there is a connection problem between the Nest and Vivint security, which both companies say they are working on a fix. It's not really an issue because I can control the thermostat from my app.
Even though I didn't give it 5 stars, I do still highly recommend this product and have actually already talked several friends into getting one. For someone who is away from the home alot, the Home/Away assist is a great tool, though it could be more accurate (which is why I only have 4 stars). Roughly half the time it doesn't kick into away mode and I have to manually do it from the app.
I bought the Nest E Thermostat for the rebate that my gas company offered originally but I cant begin to tell you how impressed I am with this product. Easy to set up and easy to use. I find myself monitoring the thermostat via the Nest app just to see how it works from when I'm away from home. I highly recommend this product.
