Appalling products, been in our house since August 2020 have got through 2 smoke detectors as they have failed, 2 thermostats in our living room, 2 thermostats in our hallway and a homelink system. Google have replaced the units each time but we have had to pay for the installation and then it's difficult getting reimbursed and haven't been reimbursed to date. As I speak one smoke detector and 2 thermostats are acting up again, just garbage, avoid like the plague!!
