I purchased a Nest T-stat at the end of November. It worked a couple of weeks and then stopped working. It wouldn't detect any of the wiring. They agree to replace it as part of their warranty but they are sending me a refurbished unit instead of a brand new one. To make things worst is that if I don't send the defective unit back, they will charge me for the price of a brand new unit ($129.99). Be honest with yourself and at least charge me for the price of a used one. I am pretty disappointed by Google. I would understand if the unit was broken due to user error or if it was past its warranty, but replacing it with a used unit after less than 2 month, this is unacceptable. Rant over.
