I got this item to replace a 10 year old same model First Alert carbon monoxide detector. Old detector working fine but I decided to replace it. Fortunately I never had a CO leakage but I checked the test button every few weeks to ensure it was working.

This First Alert Carbon Monoxide Detector was exactly what I needed — simple, reliable, and easy to set up. You just plug it in, and it’s ready to go. I love that it also has a battery backup for extra peace of mind. A great choice for quick, worry-free protection!

These little units give a sense of safety in knowing should we have a CM leak, they would let us know. Obviously, unless you have one, you cannot be sure that they do what they are supposed to do, but I am assuming they would. They are easy to figure out, inexpensive, small, and have a sharp alarm sound similar to a smoke detector. I did replace my other unit which was 3 or 4 years old because the red lamp wouldn't go off on it and it says that usually means it's gone bad. Should the alarm go off, it gives a beep which is how it is "read".

Purchased as a gift for my young adult grandsons. Tgey only needed to plug them in to get the safety benefits.

A must have in every home, we even put one in our camper.

Priced rough and gives me a sense of piece.

Works! Bought a new house and decided to put this in basement utility room. Few days later on a cold day it started going off intermittently. Called fire station and sure enough our boiler was improperly vented to outside so carbon monoxide was leaking in every time it ran (heated garage floor). They also found a gas leak when here too so this little thing saved us.

Ended up getting this sooner than expected. It is so easy to ready and replace the old one. Very happy with it.

Happy with how eazy it was to install

Having issue with one let’s than a few months after purchase

Just as expected

love it and great price
