      For being new, it was smeared on the copper finish and not in the original box. Basically bubble wrapped and stuck in a box. For $20 could have gotten a brand new one. Bottom line it works but delivery was several days late. I will check with Google to see when the warranty runs out.

      Nest smart thermostat

      Nest thermostat is a beautiful unit and easy to use though I will recommend having professional installation. Love it so much we changed all our smoke detector alarms to the corresponding carbon monoxide/fire alarm units in our home. Total overhaul was pricey but worth it and they look great.

    • Great thermostat

      I had a 1st generation Nest thermostat. When I replaced my 20-year-old HVAC system, I purchased a Nest 3rd generation because it could support multi-speed AC/furnaces. It has many more features on the 3rd generation than past versions. These thermostats will save you a lot of money over time by saving energy.

    • Amazing Device.

      Smart, beautiful and easy to operate Nest learning thermostat that really save you money in the long run when it learns your cooling/heating habits. I bought the copper finish and I couldn’t be happier. Love it!
