I bought a Nest google thermostat from google that had a 2 year warranty. 18 months later the thermostat power unit packed in and I was left with no hot water or heating. To get a replacement I had to buy a new one through google which would take 2 weeks to arrive and then I would have to claim my money back. The new one would only have a 6 months warranty and this meant I could be in the same position in another 18 months time. As I was in very difficult situation I went out and bought a different thermostat from a more reputable heating company and asked google to pay back my money for my original purchase. Even though I have had to pay twice for an electrician to fit the thermostats so am significantly out of pocket they have flatly refused to give me my money back for the original cost of the thermostat.I will never buy another Google product and will be going to small claims court as I am within my rights under the consumer rights act to claim my money back. Please stay away from this company!
