(6 pack) Kidde AC Plug-In Carbon Monoxide Detector with Battery Backup, CO Alarm with LED Light Indicators

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.

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.

we bought this because it's the exact same brand that we bought last time, I installed the last one in February of 2016 and in May of 2026 it started beeping saying it was time to replace. it actually lasted as long as it was supposed to and it is smart enough to tell us when it's time to switch and get a new one.

I had a faint chirpping in my house... You know that sound. The sound of something somewhere that chirps every 1 to 3 minutes. Driving me crazy!!! Thought I needed to locate smoke detector. Cleaned all of them dusted with canned air. Come to find out the carbon dioxide detector only lasts 10 years. Check your date on the back. These are easy to use. Comes with one battery. Plug in the wall and pull tab before.

These units have an internal clock that starts the 10-yr end of life alarm. Have a spare on hand. When the time comes it may be while you're sleeping. There is a button[s] to push to silence alarm, keep it checking for CO and replace it at a more convenient time but I didn't remember that at the time.

Can't beat the ease of use because it is a plug in device. Tested alright. I expect it will live up to warranted life of 10 years. Peace of mind since previous unit reached end of life all of a sudden but Walmart delivered within 24 hours. Only negative is that these have become very pricey. Thank you, Walmart.

The only complaint I have about this carbon monoxide detector is that on a few occasions it randomly beeped/chirped. I have it plugged directly into the wall outlet and there's nothing obstructing the detector. I have owned several of these over the years and never had any issues with them just this one.

I received two separate alarms, not a two pack. They were both in the same shipping envelope. The box one of them came in was heavily damaged and the alarm had obviously been removed, handled, and replaced in the plastic bag it came in. It was dirty and had a small plastic spur on the back broken off. The seller was trying to unload an alarm that had been returned damaged. At the least, this is very shoddy business practice. I expect better treatment.

first of all it was used which was supposed to be new! it doesn't work and it is taking a lifetime to return this!
