Compact and easy to use

I wanted a plug in co2 detector for my office and also for traveling. I also needed one I could easily reach when it starts chirpy low battery. This fits all needs. It's easy peasy to open and just plug in since batteries came with it. I wanted one that used replaceable batteries as the sealed type with lithium batteries cannot be replaced and, in my opinion, fail before the 10-year life is up. I wish it was also a smoke detector but it's not.

Necessary for safety

We needed to replace our two carbon monoxide detectors because they said to after 10 years. Well sure enough, 10 years and two weeks after purchase they needed to be replaced ( it will beep constantly when it's time ). We decided to stay with the same brand because it's been very reliable. We have one in the kitchen because we have a gas cooktop and we have one in the basement for the hot water heater.

Kidde is a most trusted brand. This just plugs into a wall socket. Easy peasy. A carbon monoxide detector is an absolute must for every household. Don't put off getting one. Carbon monoxide is colorless and odorless. You need a detector. Too many deaths that could have been avoided occur every year due to carbon monoxide. You could actually take this one with you if travelling since it just plugs in to any electrical socket.
