We bought a nest for our new home and fell in love with this little device. The settings that allow for the ac not to work as hard while we are gone, saves us money during our long 12 hour days. We use an app that allows us to track our kilowatt usage and the difference in savings is amazing. After using our first nest for over a month, we bought a second one for our other unit.
The Nest Thermostat E has worked great from the moment it was put on the wall. It is very simple to understand for daily use. It works great from my iphone or just turning the dial on the wall. I like having it in my home.
Finally Nest offers a thermostat that does what Ecobee has for the longest by adding room temperature sensor to thermostat as add on option. Works great and now my house feels comfortable in every room. The cost is now affordable and I bought 3 room sensors with it. Super happy.
I own three Nest Thermostat E's, one Nest Thermostat (the fancy one) and 6 Nest temperature sensors. All are great products but the E definitely has the best bang for the buck! Does everything the high dollar one does except search the web and tell you the local weather (I know you have a few other ways to get that info).
The initial setup was somewhat more complex than it should have been. A few glitches, like the heat coming on instead of the A/C. However, once we got through the setup, it worked perfectly! I love the fact that I can program it for the week. I really love the ability to modify the temperature from my phone. I have seen a slight decrease in our electric bill already.
