Good product

Overall, I like the product I am not sure how well it works since we have not had a carbon monoxide problem. I do wish that it were a combination, carbon monoxide and smoke detector. It’s just another thing I have to have set up somewhere.

Great for minimal outlet placement
21 days ago
This is perfect for a place where outlets are not in large supply. I have this in my daughter’s room where it is hidden behind the recliner. This corner is our designated outlets used corner since the recliner put it out of sight out of mind so it was perfect to simply add a command strip and have it in the perfect location close to the floor where CO2 would be.

Compact enough to not be too obstructive on the wall
23 days ago
This is a nice compact CO alarm that is really simple to use and maintain. Install was easy, and it came with screws and drywall anchors.
It didn't indicate mounting height, so I looked it up and found that dedicated CO detectors can be mounted anywhere as long as it isn't on any dead air spaces, so I chose around eye level.
The operating instructions are clear and you can test it by pressing and holding the button for 1 second. It also has a green light that flashes when it's working correctly.
I only have a couple gas appliances, so hopefully I'll never have to test the accuracy of this device, but it does give me peace of mind.
