I have been using this product for over 3 years now and it has been a great addition to our smart home. I like the ease of use and the fact that you can set up rules and schedules to help us get to our goals. I have not found anything I dislike so far and I hope to continue using this product in the future. There is not much that I dislike about this product. We have been able to save a lot of energy in our home. We have a few clients that have not been able to find a smart thermostat that works well with them, so we have been helping them set up the ecobee thermostat as well. I love how easy it is to use this product in our home. The customer service is also amazing. This product does everything we needed/wanted it to do. It was not easy for us to set up initially but once it was all done, the setup was super simple. We are saving money by using this product and we have complete control over the temperature of our home. We were able to get rid of an expensive thermostat that we used to own.
