Seven First Alert SMC0210 smoke detectors, with their mounting brackets and at least nine years of life left in them (manufactured May 2025).
We replaced them because a couple of them were generating too many false alarms and we didn't want to deal with it anymore. They may work better for you if you give them a try. 🤷
