4 of 5 Replacing outdated unit. January 20, 2021
Reviewer: BengiPC from HOPKINTON, MA United States  
Pretty easy, just remove old unit, remove old mount piece, screw in new mount and plug in the wiring. The hardest part is disconnecting the old wiring plug. line up the new unit, push it up and twrist till it locks in position.

5 of 5 Quality product at a good price delivered quickly November 30, 2020
Reviewer: FJH from Hinsdale, IL United States  
I have bought several smoke/CO detectors from Smoke Alert.  Their low prices and quick delivery keep me coming back.  This time, I had trouble submitting the order online, but their team in the office placed the order for me.  There was some trouble getting through to sales, but I will chalk it up as a fluke.

5 of 5 No more chirp November 6, 2019
Reviewer: robert calnen from west hartford, CT United States  
worked like a champ...direct replacement of a 10+year
old 9120B alarm that probably needed an internal cleaning.  chirp is disgusting but the new unit fit perfectly and made me happy that it is still in production.    thank you,     chirp is gone!
