Kidde Battery Operated Carbon Monoxide Alarm with Digital Display KN-COPP-B-LPM

I hardly ever leave reviews for anything, not a influencer, and not getting paid for this review, but I thought my recent experience was pretty important. I've had this model Carbon Monoxide Alarm since 2018. It is now 2025, with it never alerting me once of carbon Monoxide in my 1Bd condo for the past 7 years. I wasn't even sure that it was actually working as intended. Push button test indicated that it was working but how do you really know. Well, the other night, I woke up at 4:00am hearing a high pitched beeping. At first I thought it was my UPS (uninterruptible power supply) for my computers with a low or dead battery, as it sounded similar, which I had to replace the batteries in before over the years. Then checked my smoke alarm, it wasn't that either. Finally checked my carbon monoxide alarm, an it WAS the source of the beeping with the window panel showing 38 PPM. Thinking the battery was low, and I didn't smell anything, I checked the battery indicator that wasn't blinking red, I just reset the unit. After resetting, it started beeping again with the PPMs climbing back up to the same 38 PPM as before. As I looked around wondering what was causing the alarm to go off, I noticed that one of my stove burners was still on low/warm from the night before as I was keeping dinner warm then. My own very stupid mistake. I quickly turned off the burner, opened windows and doors to air out, and a few minutes later the PPMs began to drop on the alarm, and then finally dropped to 0. This could have turned into a much worse situation. Soooooooo, I know that this unit does work, and I'm so glad that it did after 7 years, and with the same 3 Kidde AA batteries that it came with. Not sure how accurate this unit is, but it did alert me, and I'm very grateful for that. I definitely trust this particular model despite other reviews that I've read here on this Kidde website. I actually just bought another one, with the exact same Kidde model. I'm hoping that it performs as well as my current one. Just wish the alarm was a bit louder or had a different alert sound to choose from. Either way, I'm very happy all is working fine.

Great carbon monoxide detector! Can hang or set!

I received the incorrect product; although the packaging appears identical, the device inside the plastic pack differs from what is shown in the image. Upon closer inspection, the logo on the product is also different from the one listed. This discrepancy is misleading and constitutes a form of deception, adversely impacting my business. I can provide images to illustrate the distinction between the correct and incorrect products. I don't want you to send the wrong product to anyone else.

I would love to rate this item, the Kidde Battery operated CO alarm, but I havent received it yet. I ordered it Nov. 30th. The tracking check indicates it was delayed on Dec. 4th and I havent heard any update since then. Please direct your attention to this issue. Thank you.

I didn't realize the carbon monoxide detector needed to be replaced after so many years until a month ago when the one I had started chirping and had someone telling me buy a new one. I started reading the information on some that wall mart sells and the comments from people. I was very glad to have a place to go and get the information that I needed.
