Best Household Improvement Ever!
I'm a new homeowner and not yet secure in my DIY skills so I asked my brother-in-law to help me install it, but in truth I could have done it myself! I specifically purchased Ecobee to work with our Amazon Echo and so my husband who has MD can control the temperature and it is perfect!

Great Customer Service
I love my Ecobee3! We are renters, so this was a big undertaking for us to replace the thermostat that came with our apartment with a digital thermostat. But our air conditioning bills were getting crazy, our thermostat was very unreliable (it would randomly go up to 85 degrees in the middle of the night or other times for no reason), and we wanted to be able to control it from outside the home. We briefly considered The Nest, which has some great rebates from our power company. But after poring over reviews, we decided to go with the Ecobee, mainly because it was Home Kit compatible, and we may want to use that in the future since we have an Apple home network and Apple TV.

Great for too-hot-in-summer and too-cold-in-winter rooms
Product is great (and arrived fast). We needed our baby's room to have a sensor as it is always hotter in the summer and colder in the winter, as it was a guessing game with the original thermostat downstairs. After having 2 professional HVAC people come over and telling us there's nothing we can do with the ducts to improve the situation, we compromised for a smart thermostat to at least eliminate the guessing game (I would still want to change our HVAC configuration, but that's a 10k job).

I'm in love with my ecobee
I'm in love with my ecobee. Upgraded from an old non-programmable Honeywell thermostat. So far, my HVAC seems to run MUCH less than with the old thermostat. I love the programmable schedules, and the sensor modules. I also installed the unit myself using the Power Extender Kit, and it was super easy. Really looking forward to lower energy consumption (and costs!) with this thermostat.

Great purchase
Better than Nest in that it has discrete external sensors to focus on rooms you care about the most. Easy to program schedule. Set up was overall pretty easy. Love that I can control the temperature on my cellphone. Similar to Nest, it is a good-looking modern product but with (in my opnion) a more pleasant display and touchscreen.

The functionality and ease of use of this device is amazing. I'm already seeing the energy savings
The functionality and ease of use of this device is amazing. I'm already seeing the energy savings. The sensor system is simply brilliant and the fact that they have motion detectors is amazing. The app is very easy to use and a breeze to setup with apple home. I will be purchasing additional sensors to make it even more smarter around my house. There is a lot of technology here, which is the main reason I choose this over the Nest and also a 3 year warranty.

Best Thermostat On The Market!
I really believe this is the best thermostat on the market. You can place multiple external sensors around the house so that the Ecobee3 (E3) knows that the temperature is in different parts of the house. Since the E3 knows both the temperature in other parts of the house AND if someone is present, it can dynamically "care" about the temperature only in rooms that have recently seen occupancy!
