Having used several different programmable thermostats I found the convenient application and ability to use an app to create program schedules the only way to go.
The Nest E was easy to install in 4 house heating zones and performs flawlessly for a year now. The latest Nest App fails to stay compatible with iphone4s , but used to be until the latest app code release. This is unexceptable!
Sometimes I argue with my friends about who's thermostat is better, and then I realize I'm arguing with them and they have the regular Nest thermostat and I have the Nest E. Haha, I'm still right. I love my Nest E thermostat. You will be very happy with the Nest E it works amazing and it looks great too.
Great experience from install through daily use. We did it all ourselves. Easy hardware install, easy software setup, and pleasing daily use at home as well as remotely. Painlessly integrated right into our Google Home setup and smart display. Saves us $$$ on heating cooling costs while keeping us comfortable.
