Bests & Worsts Reviews from Amazon

Thermostat worked fine for 6 months then I woke up to a cold house and the thermostat displaying a "LOW BATTERY" message. I took the thermostat off the wall and charged it via the USB port and put it back on the wall. It worked - but only for an hour or so and then the low battery message appeared again. I found an article that there is a known issue with a software update causing this - support was not interested and offered nothing in the way of help. Now I have a $ 250 piece of junk hanging on my wall. Since this happened I have found numerous postings online from people with the same problem. DO NOT order this thing, if I could give it zero stars I would have. It is amazing that Nest thinks it can charge $ 250 for a thermostat that dies 6 months later and people aren't going to be upset....
