5 of 5 Go To Comapny August 14, 2019
Reviewer: Anonymous Person from Columbia, SC United States  
Smoke Alert has become my go to company when I need any First Alert BRK alarms. The price is the best I have found and shipping is free and they carry alarms that most stores don't carry. They ship timely and my orders are accurate to what I receive.

5 of 5 Great Smoke Alarm, easy installation March 20, 2019
Reviewer: John Wilsterman from townsend, GA United States  
I wanted a smoke alarm that would fit the footprint and wiring of an existing, outdated smoke alarm. The First Alert 9120B fit perfectly and each was installed in less than 10 minutes. This smoke alarm also guards against carbon monoxide. A great buy!
