Customer Rating: - Carbon Monoxide Detector
This product works as advertised. It is simplicity itself to install, and does not cover up all outlets when plugged in. This indicated to me that some thought went into its design. I purchased 2 units, and both are working perfectly.

For the price you can't beat this. Just plug in and no expensive batteries. Very simple.

Customer Rating: - No Brainer!
I chose this alarm because it was the easiest to use. Just plug it in and that's it. I have a gas fireplace and was told that I needed a carbon monoxide detector. Plugged into a regular outlet, it has a dim light to let you know that it's working and you can test the monitor at any time to make sure it's "alarmed." Hopefully, I'll never have to see how well the monitor works in an emergency but I feel safer knowing that I have one.
