Review: Reliable, Easy to Use, and Gives Peace of Mind 🏠⚠️ - I purchased the Kidde Carbon Monoxide Detector for my home, and it has been excellent. The plug-in design with a 9-volt battery backup is very convenient, ensuring continuous protection even during power outages. The digital LED display clearly shows CO levels, which is helpful for peace of mind. Installation was straightforward—just plug it in and insert the battery. The alarm is loud and responsive, and the unit has a solid, durable feel. I also like the compact design, which fits nicely on any wall without being obtrusive. This detector gives me confidence that my family is safe from carbon monoxide, and it’s reassuring to know it’s reliable and easy to maintain. Simple to use, highly dependable, and a must-have for every home.
Review: Quality CO detector. Worthwhile investment. - Quality Kidde brand CO detector. I replaced my original one with this identical one after 10 years of service, when it finally beeped and showed "END" in the display, which renders it useless, which is by design. Ironically, I never had any CO issues or alerts, until about a few months before its 10th anniversary in service. My home's natural gas boiler was over 25 years old, and begin leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded. Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detectors audible & visual alerts. Hope they're still making this model 10 years from now, when I will need another one, or if I decide to move and want to purchase a new one. It's certainly not the cheapest CO unit on the market, but it's a good value for the money. Oh, it plugs directly into any standard 110-volt power outlet and it has a 9-volt battery backup, battery included. Although they recommend you replace the 9V backup battery every few years, I never replaced mine, and it was still almost as good as the day it was installed. My Kidde CO detector is plugged into an outlet in our upstairs hallway just outside of our bedroom. Fortunately, it also fit perfectly next to (below) my plug-in doorbell, which was a huge plus! I'm planning on installing one in the basement, near the gas boiler as well. Should have done that years ago, as we would have likely received an earlier "heads-up" that there was a combustion problem with the boiler. One last note: You can remote wall-mount this unit also. Cool feature! If you look at the last picture that I posted with this review, you can see that when the rear access cover is removed to access the backup battery, there is extra cord stored on the opposite side of the battery. The connected main power source plug can be easily removed and relocated/extended, via the corded connection, in order to have the CO detector located somewhere other than directly plugged into the power source. There is also a handy little clear plastic packet included, containing two wood/mounting screws and two wall mount plastic expanding inserts. (Not shown in picture.) Just can't say enough good stuff about this unit. Very pleased with it!

### ⭐⭐⭐⭐⭐ Inexpensive insurance.
*by K***R on January 20, 2026*

I have a number of these throughout our house. They have worked flawlessly. They alerted once when a carpet cleaner turned on his generator while his vehicle was inside our garage. Numbers were high enough that the fire department ventilated our house. Could have been a disaster had they not alerted us. This purchase replaced a similar one that failed after many years. Made in Mexico now, but I expect the same performance. Battery backup is important to me as we experience frequent power failures.
