I’ve had this exact carbon monoxide detector in my home for the past 10 years, and it just recently gave me a notification that its life expectancy had expired. After a full decade of flawless performance, I didn’t even hesitate—I went out and bought the exact same brand again.Installation is super easy. It plugs right into any standard outlet, and I really appreciate that it also includes a battery backup. That gives me extra peace of mind knowing it’ll keep working even if the power goes out.What I value most is how reliable it’s been. It clearly notifies you when there’s an issue or when the unit needs replacing—no guessing games or worrying if it’s still functioning. It’s one of those quiet protectors in the background that just does its job.

The KIDDE carbon monoxide detector was very easy to install. It came with the batteries already in it, and all I had to do was pull out the yellow plastic tab to activate the batteries and plug it into a wall outlet.Then a test beep will sound and a green bar appears on the unit.It comes with a detailed instruction booklet and also a warning label stating what you should do if CO is detected. The instruction information states that the unit will last for 10 years. I’m not sure about the battery life, but there will be low beeps to tell you when you need to change them.

I picked up this carbon monoxide detector for our upstairs hallway. I didn’t want anything overly complicated, just something reliable that I could plug in and forget about unless something actually went wrong. So far, this one has been exactly that.Setup took less than a minute. I plugged it into a standard wall outlet, hit the test button, and the alarm sounded clearly and loudly. It also has a battery backup, which is important for me since we live in an area that gets occasional power outages.The design is compact and doesn’t block the second outlet, which is a nice touch. There’s a small indicator light that shows the unit is on and working. No screens, no digital readouts, just basic, no-nonsense monitoring.Pros:- Plug-and-go setup- Loud, clear alarm- Backup battery included- Doesn’t block both outletsCons:- No digital display- Carbon monoxide detection only (not a combo unit)- No smart features for app alertsI’ve had it running for about three weeks and it’s doing exactly what I need. It’s ideal for anyone who just wants a straightforward CO detector without extra tech to manage. If you want something you can pair with a phone or that also detects smoke, this might not be the right model. But for basic carbon monoxide safety, it gets the job done.

This is a perfect solution to a serious concern for carbon monoxide poisoning. It plugs into the lower electrical socket and leaves the upper socket available for whatever else. Because it's plug in, that also means it is portable. Toss it into your suitcase and take it with you for extra piece of mind on the road.

I bought the Kidde Carbon Monoxide Detector for extra peace of mind, and it has definitely delivered. It’s compact, easy to install, and gives me confidence that my home is safer.Setup was incredibly simple — I just inserted the batteries and it was ready to go. The instructions were clear, and mounting it on the wall took just a few minutes. If you’re using the plug-in version, it’s even easier.

Easy to use and a good price. I purchased to take on vacation with me. I have heard horror stories, so I wanted to keep my family safe from carbon monoxide in our hotel room. The only bummer was that I left it at the hotel! But I will be purchasing again before I go on another vacation!

We’ve used this for a while! They have a 10 year life span, and help us feel better about our gas stove. Super easy to set up, and VERY loud when it goes off- so you shouldn’t have any issues hearing it
