Review on 🏠 White Google Nest Protect S3000BWES - Battery-Operated Smoke and Carbon Monoxide Detector by Sherman Lancaster

I bought three of these units expecting them to work better than they actually are. One block continues to report there is smoke in the room, although there is no sign of smoke. Other blocks do not report when one of the blocks is in alarm mode. I contacted Nest about my issue and they advised me to send a new device. Instead, they sent batteries. When I called back to speak to them, they told me that my device was out of warranty and that there was no one who could help me resolve my issue. I was a regular customer who bought a thermostat, two indoor cameras, two outdoor cameras and three smoke detectors. But it seems to me that if I spend $100 on a smoke alarm, it will last more than two years.
