Review: Smoke alarm - Good product, good service. I think I got a rogue faulty detector as it started beeping later that day with no smoke present.
Review: Terrible product - Purchased and installed on 4/1/26. Had previously purchased similar model which certainly did not last 10 years but stayed with this brand since all brands had questionable reliability. This was a mistake! On the 18th of May around midnight it started beeping. After checking throughout house for signs of smoke I decided it was a malfunction and disabled it. Forget the 10 year sealed battery, it did not last 2 months! Similar complaints about the Kidde but I will get one that I can replace batteries and not depend on the “ 10 year sealed” battery. For something so important I do not understand the poor reliability from two supposedly dependable companies!

### ⭐⭐⭐⭐⭐ Reliable Brand.
*by M***. on 7 June 2026*

Easy to install. Slightly bigger than the one I replaced. I never seem to get 10 years out of these sealed 10 year batteries. Its ok though this brand performs well and I don't have to think about it again for at least 5 years.
