This is a great, sturdy smoke detector for larger rooms in our house. It's easy to install. Batteries included! I'm glad I purchased this! Also, glad there is a smaller version for our smaller rooms. When we moved into this home, the smoke detectors were over 10 years old & they were beeping incessantly because the batteries were low. They left wires dangling from the ceiling when we had to remove them. After installing this a couple of months ago, I can tell this is a quality product! Of course, it's nice to have peace of mind for our safety! I'm purchasing another one for our hallway, and I have recommended this brand of smoke detector to my family members for their homes.

Only had it a few days but it went up without a problem. Filled in the old holes of the previous detector and drilled two new ones. Easy. Used the plastic inserts for the screws. Left the supplied dust cover on the unit until ready to test. Looks good, too, not as ugly as the main competitor's unit. Like that it's 2 AA batteries rather than 9 volt.

I like these smoke detectors, in general, as they do not react to cooking odors, However, the level of the actual alarm leaves something to be better desired. It is just not up to what level I expect an alarm level to be,.. to get a person's FULL ATTENTION!!...but at least I don't have any more false alarms from cooking vapors any more. THAT is a DEFINITE PLUS for this unit

I got it as replacement for Kidde hardwired alarm which started beeping because of the aged battery and was glad that this new one fit in the old base. It saves a lot of work and possibility of ruining the ceiling. Since it works on ordinary AA batteries, it’s easier to maintain.
