Easy to install or mount in each room.

I appreciated not having to remove the batteries from the older models but worried about throwing them into the trash as it was written on package. Checked with the city to make sure it was to just trash the old models.

Bought 3 and a half months ago. Was triggered by a smokey kitchen. After that, started going off sporadically. Bought the more expensive 10 year ones but not worth it if they malfunction after less than 4 months.

I like that the batter lasts the life of the alarm. I did not like that the ceiling screw hole patter was different from my last First Alert alarm. Hopefully I will never have the information to do a full review!

It’s convenient to have both carbon monoxide and fire detectors in one, especially for the small apartment I bought it for.
