Google Nest 3rd Gen Thermostat - Pick Color (Open Box)

We still installed it even though it had previously been used, but there was a reason they returned it too. There was some sort of error inside this Nest where it would always resort back to ECO function, no matter if you turned it off and set all your function capabilities to exactly how you wanted them to be. I would come home and my house would be 71 degrees fahrenheit, when I would have liked it to have stayed at the 68 degrees I turned it to before I left the house at 5am. It had a mind of its own. We researched every trick in the book, and followed every single persons advice out there on the internet on how to avoid this from happening, but on the 10th day when it STILL happened - I snapped, I was done. I wanted my old school thermostat back, and this thing could rot for all I cared. We carefully wrapped it back up and sent it back.... I really hope they got rid of it this time, instead of just marketing it as "refurbished" or "used" however they market it.... I hope it's just off the market this time. Now, most people do not have this issue with the Nest. If you like a thermostat that will ADJUST to your needs and anticipate what you might like your setting to be on, then this might be perfect for you....and in your case I wouldn't have given this one star - I would give it 5 stars, b/c yes, it anticipated my needs, but my needs were anticipated wrongly.... maybe I just didn't give it enough time to learn my daily habits.
