Kidde 4-inch 10-Year Sealed Battery Ionization Smoke Detector with 85 decibel alarm and Hush, 2 pack

from Tricia

these are really convenient and whats better than not having to have to change batteries and the horrible beeping.

from Heidi

These are small so don't take a lot of space but they are loud I think they are perfect

from Maureen

Very easy to install, I was able to use the 2 screw holes from my last detector, plus the battery lasts 10 years I liked that, if I need more I would definitely buy them again

from Lisa

Sealed 10 yr battery!! What a relief as we age not to have to get on very tall ladders for the alarms on the stairs ceiling. It's very high up. And we have two sets of stairs in our town house. Great idea to seal those batteries!

I didnt have to fight to get the battery in, easy to hang up. Only required a stick and twist to turn on! Tiny but sounds mighty an with my cooking skills, has easy push mute button, so I can burn that water... Hey my husbands the real chef!
