Kidde 21008873-4 KN-COPP-B-LPM Battery-Operated Carbon Monoxide Alarm with Digital Display, 4 Pack

Easy to put up and works great!

I hope it is accurate. So far it's been reading 0. I like how easy the install is and the digital readout.

Arrived as promised. Seems to be working well.

I got these for my husbands semi and the house, Often times riding in the truck with him I have complained about the exhaust from other trucks or even smelling what I perceived to be our exhaust at times and decided to get a couple for the truck The first night it went off not very high level and can't really attest to the accuracy of it not knowing what the levels really were we feel safer knowing its in there. As far as the house goes got to thinking not sure if I need it I have ac and a heat pump all electric don't park in the garage so was trying to think why I would need them in here so I haven't used them yet until I can find a reason to put them up. Let me know if ya think of something.

These saved my families life. Had a power outage and our whole house generator had been running for 6 hours. Unbeknownst to us the installer of the outdoor generator installed it right next to a vent in our crawl space. When they ran the electrical line they forced the vent open in the crawl space. The carbon monoxide entered our crawl space and then our alarm in our basement went off first at 76 PPM. We fleed the house and called our local fire department for assistance.If we didn't have these alarms installed we would've gone to bed that day and probably not woken up.Thank you Kidde for saving my family!!!

Great product, like being able to place it anywhere without having to mount on the walls.

This carbon monoxide was easy to set up and install. In my opinion it looks pretty good too.
