So Far So Good March 26, 2014
Reviewer: Matt from Fairfax Station, VA United States  
I replaced my 12-year old smoke detectors because they were always malfunctioning and going off. I replaced the bedroom detectors with FA3120Bs and they have been great so far.  No false alarms and installation was a breeze.

Reviewer: Wayne Lewis from Milan, IN United States  
Ordered on Saturday, had them on my doorstep on Monday!!  What a breeze to install. Removed my old alarms, wired the new pigtail up to the existing wire's, put up the new bracket,s, slid in the battery  and turned the power back on, and tested.  AOK.  Smooth as silk.
