Warranty for nest thermostat I purchased a NEST thermostat in December of 2019. Since then, it has broken 3 times, and Google has sent me 3 replacements. After the third, I switched to a different brand and told Google i wanted to return the thermostat for a refund since their product is obviously defective. They refused. They told me they could continue to send me replacements for the two years until the warranty was up at which time I was out of luck! I want my money back for this defective product!
