What Customers Are Saying
Customers praise the 10-year sealed battery for eliminating annual maintenance and the intuitive, quick installation that requires minimal tools. Many appreciate the slim design that blends seamlessly into walls. However, a notable group reports units failing within one to two years and triggering frequent false alarms from perfume, air conditioning, or unknown causes, disrupting sleep and eroding confidence. While most value the convenience and peace of mind, reliability concerns temper overall satisfaction despite the advertised lifespan.

Would RecommendWe needed a new smoke detector and shopped at different stores in town. This product met our expectations and was better than others offered at other stores based on price and features. I like the features of this alarm. It was easy to install.

10 year battery smoke detector
Would RecommendEasy to open. Easy to install. No more battery checks. No worries for ten years
Meh
These go up like most at first (two screws for the mounting plate, then twist into place). It does not lock at all, so it's a bit loose unless you use a separate screw. The room customization is quite irritating to set, but you don't need to do it for the detectors to work. Otherwise, they are pretty much like any other detector. No false alarms so far. Good enough.
FIRST ALERT HAD TO REPLACE FOUR
Would Not RecommendI had to have four new ones replaced by the manufacturer within a year. They went off for no reason. You can only "turn them off" with a switch and they are not able to be used after that. First Alert did send me replacements but still.
Hi Rose, thank you for sharing your experience with us. We appreciate you giving our products another chance and are glad that replacement units were...

I bought these to replace a couple in my house that had randomly died. These were easy to activate and install. One fit on the existing bracket and just clicked right in. The other didn't fit, but I was able to take off the old bracket and fit the new one into the same screw holes with the included screws. Test worked fine and I've trusted it since.

Great product
Basic and Easy
Would RecommendHad one go out in my kitchen. Grabbed the 2pk to replace it and the one in the hallway since they were installed at the same time. Installation was a breeze and the long battery life is a plus.

10 yr battery life
Would RecommendProtect your garage and not just your living area.
Would RecommendWe bought this a month ago and are so glad that we did because only our main living area is wired with fire detectors yet a neighbor lost their entire house to a fire that got out of control in their garage so now we have smoke detectors in the garage and lower utility area where battery operated devices could catch fire.
