Easy Install May 19, 2017
Reviewer: Anonymous Person from South Bend, IN United States  
The alarms ordered replaced the same model that had been in service in my home for 10 years.  Therefore, installation was easy since all I had to do was unplug the old unit and plug in the new one.  I guess you only really know how good the unit is if you have a fire and the alarm sounds. I've not had any problems with this model alarm in the past and don't anticipate any in the future.  It was nice that a battery was included.

BRK Smoke Alarm January 4, 2017
Reviewer: Charles B from NY United States  
Replaced all my 9120B alarms. The BRK I had were 11 years old. I stuck with BRK because I feel very comfortable and safe with them.
