Appears to be a great value. I can't say how good it works yet because you can't smell or see carbon monoxide. If I'm still alive in 10 years it's either because it worked or I haven't had a carbon monoxide leak in my house. I did buy 2 of them because I wanted something to protect my family and I don't have a lot of money. I also bought 6 smoke detectors because out of every place I checked Home Depot had the best price easily. I think that they might be doing this on purpose to help keep people safe. Thank you Home Depot.

I’m so happy I bought this. I’m 60 years old and I’ve never had a carbon monoxide detector ever. Now I don’t have to worry about the deadly gas coming into my house killing me my pets and family. I only got this because the mortgage company made me. I don’t know how over the last 60 years I could of slept in this house without one. I know Greta Thunberg would be so proud of me. Now I can prance around my house safely and happy while listening to The Osmond Family album.

We purchased two of these detectors. We have a new house that has interconnected smoke detectors, but when I read about them it did not say they detected carbon monoxide. We have an attached garage, a gas fireplace and a gas furnace. Carbon monoxide could come from any of these. We would rather be safe than sorry. This detector is relatively inexpensive and easy to install. I would recommend it to anyone.

How can I rate a CO detector I just purchased? I really was looking for a battery replaceable version. The reviews for 10 year devices is not as high as I would like.

Hello FarmerDoug,
We hope that you never have a carbon monoxide issue, but to clarify, the sensor is the same on all carbon monoxide detectors.
Easy installation and it works.
