Amazon Reviews, 4.2 out of 5 stars
Easy To Use and Install
The ecobee3 is a small, light and easy to install thermostat. It looks sleek on the wall, and is quite small compared to the old boxy thermostats. It's touchscreen and very intuitive to use. I like that it works over the WiFi, and doesn't require another hub or device to work with it, like my old Z-wave thermostats. You can control the thermostat with your smartphone, which is the real benefit of these devices. I like having the ability to change the temperature on the fly and not have to walk over to my thermostat. You can program it, or change it via the smartphone whenever you need to. The touchscreen function is one of my favorite features. It's so simple to use that even my non-tech savvy folks can adjust the thermostat if need be. You simply slide your finger up or down and change the temperature...

the finest customer service department I have ever encountered anywhere.
I'm going to concentrate this review on the installation process. I love the product, it works exactly as described and looks OUTSTANDING once installed. I had to call customer service twice. The first time was because I encountered some unexpected wiring at the furnace, and wanted to run it by a pro before I screwed something up. The wait time for help was zero. I was immediately talking to Patrick, who understood exactly what I was seeing at my furnace, and clearly told me how to proceed. After I had the unit installed, it wouldn't power up, so I had to call back. Once again, there was no wait, and the customer service rep figured out what I'd done wrong by looking at a fuzzy photo of a jumbled nest of wires I emailed him. Color me impressed...

Easy to set up, easy to use, even for the novice. Does not include sensors.
The highlight of this install was that it took less than an hour to complete with my minimal knowledge of electrical wiring and a few home tools. What a relief! No tedious and time consuming running back and forth from the fuse box in the basement back up to the living room, no false starts, I just hooked it up and it *worked.* I have a heat pump system with a control wire, which is probably ideal for Ecobee since you don't have to use the power extender kit...

A rare 5-star product
I only give 5-star ("I love it") reviews occasionally (check my history), reserving the rating for a product I really do love. In this case, I love this thermostat about as much as one can love a thermostat. And this came as a something of a shock to me, since seriously, it's a thermostat - and I've never had one that was better than 3 stars ("It's okay"). During my testing of this thermostat, I contacted Ecobee for help (which was prompt, friendly, and very helpful)...

Is The ecobee3 lite worth it? First impressions and instalation tips.
I have wanted to replace my older (and uglier) thermostat and finally took the plunge with the ecobee3 lite. I wanted something that looked good, worked good, and would be easy to install. Did the ecobee work out? Short answer: yes! The ecobee3 lite gets five stars in form and function. Installation had a few bumps but this still comes highly recommended...

Slick, easy to setup and efficient.
Super easy to install with the help of the app. Love the way I can turn the aircon on when I'm on my way back home so it's down to temperature when I arrive. I'm sure this alone will repay the cost of it over the years. Looks slick too. Great that it's a Toronto company as well.

Never Installed a Thermostat Before - Until Now! So easy.
This was a little daunting of a task to install the product, but I have to say that it went well. My husband and I are not what you would consider A/C experts of electrical experts, but we took this one with excitement and hope. It was an easy install...

Wonderful home-automation/thermostat. You need this for your home.
This is a truly wonderful thing. My first step into automating my home. And its beautiful. Installation took me 20 minutes (thats not quite true. Installation took me an hour, but that is because I did not read the instructions and turn off the power - I crossed two wires, had to go to the hardware store, buy a new fuse, install the fuse in the furnace, and continue. Read the instructions!!) Once its connected, it needs to be set up. The user interface is perfect! It was simple, clear and just worked. Once installed, I downloaded the app to phone and table, and then everything just worked. I can control times and temperatures, the device watches local weather reports to prepare for changes! You can tap the screen as you walk past to see the weather forecast! Yes, I know I can do that in my phone, but its so cool to be able to do that on the wall!...
