What our tester says: “These interconnected smoke alarms were incredibly easy to sync and set up. The mini size made it easy to install these alarms without them feeling intrusive. They fit nicely into any space, even a corner. When one alarm goes off, it triggers the other four along with the base station, ensuring anyone can hear the alarm no matter where you are in the home. The app makes it easy to monitor the alarms as well. I highly recommend this set for any home.” Stephanie Cronk, Executive Editor of Product Reviews
