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.

Peace of mind for my family

As a mom, safety is a top priority—and this Kidde carbon monoxide detector gives me serious peace of mind. I love that it plugs right into any wall outlet, but also has a battery backup so it still works during power outages (which happen a lot during storms where we live). The ease of use is amazing. Assembly takes less than 10 second. We put one in every room in the house even the hallway It was super easy to install—just plug it in and it's ready to go. The digital display is clear and easy to read, and it even shows real-time CO levels, which I really appreciate. The test/reset button is simple to use, and the alarm is loud enough to wake us up if there's ever a danger. Thankfully, we haven't had any issues, but it's comforting knowing this detector is quietly doing its job 24/7. Highly recommend for any home, especially with kids!
