Good deal product and easy installation
Easy installation, we tested the product and it seemed to work well. The price was excellent, it was a better deal than purchasing it at the store. It only took a minute to put up. I love the fact that the battery does not have to be replaced and hopefully will last 10 years as promised.

What’s to not like
I’ve had this very model detector in my house for 12 years and it finally gave out so I feel like 12 years is a pretty good lifespan so I just bought another one!

Good quality smoke and CO2 detector but I wish they would standardize brackets
The time finally came. Our smoke and carbon monoxide detector (also a Kidde brand) from 2010 finally died and we needed a replacement and the unholy chirp constantly reminded us. After reading various reviews from various online sources, we settled on this newer Kidde smoke and carbon monoxide detector with a sealed 10 year battery.The detector itself was easy enough to install with the included bracket but my biggest gripe is that there is no bracket standard, not just between brands but within the same brand. So to install the new bracket I had to pluck the old wall anchors out and drill new holes for new anchors because the hole pattern was different. Very frustrating because a standard set of hole patterns would allow you to utilize the old anchor points, saving time. I’m too lazy to fill and repaint all the holes so the detector is covering up decades of various bracket holes.Positives+ Sealed unit with 10 year life so no battery replacements+ Easy enough to install+ Easy to test and see function by color coded LEDs+ Detects both smoke and carbon monoxideNegatives- No bracket standard hole pattern means having to drill new holes and possibly remove old anchors

Scam Product
I purchased a 4 pack on September 10, 2025 but did not install until today 11/21/2025 so it’s past the return date. Be very careful when activating the alarm, there is a small round red button on the back that looks like a flat screw, you have to turn it to the right to activate the alarm but if you turn it to the left, it gets locked and you have to throw it away., there are no instructions and the illustration is completely wrong to fool you. The illustration shows the word “on” indication to turn it to the left but if you do it gets permanently locked and useless. In my opinion, the manufacture designed it that way intentionally. I called the 800 number on the back and their customer support agent told me that there is nothing they can do about it and told me to call Amazon to get a refund. This is not Amazons problem, it is the manufacture’s problem, they have a flawed product and bad business practices that need to be addressed.

Worth the money
Love these. Worth the money if you have gas fixtures.One important feature is that they are all linked. If one goes off in the house it signals the others to go off. I love it because if there were a fire or carbon monoxide leak on one floor of my house, everyone at home would be alerted.They are super sensitive to smoke, mine have gone off a few times when I was cooking. Referencing my above comment, this was super annoying to everyone else in the house because all the alarms were going off as well.
