Reliable and Easy-to-Use CO Detector
The Kidde Carbon Monoxide Detector has been a reliable addition to my home safety setup. This battery-powered CO alarm is incredibly easy to install and use, making it a great choice for any DIYer. The test-reset button allows for simple functionality checks, ensuring the detector is always in working condition.One of the features I appreciate most is the LED indicators, which provide clear visual cues for normal operation, testing, and low battery alerts. The low battery indicator is particularly useful, giving me ample warning to replace the batteries before the detector loses power. During testing, the alarm responded promptly and loudly, providing peace of mind that it will alert us in the event of elevated carbon monoxide levels.The only minor downside is that it doesn’t have a digital display for CO levels, but for a straightforward and effective CO detector, this is a small trade-off.Overall, the Kidde Carbon Monoxide Detector is a dependable and user-friendly choice for enhancing home safety. Its ease of use, reliable performance, and essential features make it a highly recommended product for any household.

Great for travelling
I like to detector with us when staying in hotels because you never know. It seems to work well and I like that it’s battery powered. I hope it never goes off unless I’m testing it. Gives us peace of mind while in our room.

Simple, Reliable CO Alarm for Peace of Mind
Simple, Reliable CO Alarm for Peace of MindThe Kidde battery-powered carbon monoxide detector is an easy and affordable way to add an extra layer of safety at home. I like that it runs on batteries, which makes it portable and flexible—you can mount it on a wall or just place it on a shelf without worrying about wiring. The test/reset button is straightforward, and the LED indicators give quick reassurance that it’s working.It’s very lightweight but still feels solidly built, and installation was as simple as popping in the batteries. The low battery chirp is loud enough to notice, and the alarm itself is piercing, which is exactly what you want if it ever goes off in an emergency.Because it’s battery-powered, you’ll need to stay on top of changing batteries regularly, but the trade-off is portability—you can move it between rooms or even take it on trips. For long-term setups, combining it with a hardwired or plug-in unit gives the best coverage.Bottom line: A dependable, no-frills carbon monoxide alarm that’s easy to install and portable—an inexpensive safety essential for any home.

Have had one of these in my travle trailer for over 5 years. It gave out, time to buy a new one.
For the safety, price, and over 5 years of the identical same model working great, I replaced it when it failed with a new one. When a company doesn’t change a design in over 5 years, you know the product is good.

A must have item for travel
My husband and I travel quite a bit and recently I have been hearing these stories about people who stayed in hotels in different countries and who died while sleeping from carbon monoxide poisoning. We were planning a trip to 2 countries with two other couples and after seeing these stories, I immediately decided to order these items for the 3 couples. These are very easy to use, appears to be good quality. Instructions are clean. Display is very easy to read. When tested, the alarm is quite loud and would surely wake you up from a deep sleep. We took the alarms on our trips and placed on the bedside tables. I like the fact that these are battery operated in steady of plug in. I will just change batteries before each trip. These now have a permanent place in my suitcase. Also note that it’s not very heavy so does not take it a lot of space in suitcase.Note that i am giving it 5 stars, though obviously I can only tell if it performs exactly the way it should, if I am in an area with high carbon monoxide. I hope never to have that experience but if I do and all goes well, I will be back to update. If not…. well.

Great Alarm
This carbon monoxide alarm is loud and easy to set up. It comes with the materials needed to hang it up and great directions to put outside of your room. The test alarm is loud. I can hear it from all parts of my apartment. It gives me a great peace of mind.

J’ai acheté ce modèle il y a 10 ans et c’est le terme de ce produit, alors comme les 10 ans étaient terminées, j’en ai acheté un autre identique car j’étais très satisfaite de ce modèle. Merci
