    JEFFREY -- springfield, MO   10/17/2012
    Pro: Hi Tech, Full Control from any web connection, easy to use once set up. Con: Expensive, pro install recommended but layperson can do it if some basic wiring knowledge,
    MICHAEL -- charlotte, VT   9/24/2012
    Very nice looking thermostat that was simple to install. Ecobee seemed to be having some server issues the weekend I was registering it (Labor Day 2012), so it took several attempts before success. Since then, I've had no problems with the Ecobee website. My only suggested improvement would be to enable the temperature / humidity history WHILE IN VACATION mode. Otherwise, it does exactly what I wanted.....1) to remotely turn the AC off when renters check out and 2) to remotely turn it (or the heat) on, while we are en route to using it ourselves.
    ROBERT -- rochester, NY   9/20/2012
    Great product- I rate it 11 out of 10
    Bob S -- North Carolina   8/19/2012
    Boy is this thing cool- Installed in 1 hr & works perfectly. Wifi/internet setup is a snap. This allows me to manage my entire HVAC system remote with either explorer or my Droid.
    PAUL A., -- wharton, NJ   7/14/2012
    This unit replaced a defective unit and is working properly. The other one would not go one line and stay there. This one locked up as soon as I installed the proper parameters
    BRADLEY -- denver, CO   7/13/2012
    Didn't work with my system, help/support was not helpful.
