We did a lot of research before purchasing the eco bee 3 directly from the manufacturers online.
We bought the NEST and returned it.
We also bout an extra 2 sensors for the eco bee. The system is amazing and so easy to use. The sensors tell the furnace where in the house you are and then works in accordance to your temperature setting for that room. It is amazing how the technology works. We have a sensor in our home office, the master bedroom and the main living room.
