Easy Install
Hastle free install, very loud when tested. Replaced our 10 year old units with these. No problems as of yet.

Saved my life
Installed as soon as they arrived to replace older models that the batteries had expired in (7 year batteries and no maintenance or replacement option). These do have batteries that have to be or can be replaced. The 2nd night after installation, the detector I had mounted in my bedroom (installed all 6 throughout my house) went off around 2:00 AM and awakened me. I immediately shut my gas furnace down and called a HVAC company. They found a crack in my heat exchanger as well as issue with the flue or exhaust pipe that was allowing CO to enter my home. Had I not replaced my CO detectors when I did, I wouldn't be writing this review now. Well worth my investment!! Easy installation and had all 6 up and operating in less than 30 minutes as well as reasonably priced. Purchased this pack of 6 for less that the other 2 I had bought 7 years ago.

Good value 6 Pack
My fault for not reading the description. I thought they were the plug in type. Very small, which I like and was surprised by, and looks like they will work, but they will have to be installed with screws to the wall.
