Title: Ten years of trouble free service
Review: I purchased the Kidde Carbon Monoxide Alarm ten years ago, and today, it reminded me of its reliability with a loud, audible chirp and a display reading “END,” indicating that it has reached the end of its useful life. Over the years, this unit has proven to be incredibly accurate and dependable, providing me with peace of mind regarding my family’s safety. It is long overdue that I write this review.One of the standout features of this alarm is the ease of replacing the batteries when needed. It’s a simple process that ensures the unit remains functional without any hassle. I appreciate how straightforward it is to maintain, allowing me to focus on what truly matters—keeping my home safe.Given my positive experience, I will definitely be purchasing another Kidde Carbon Monoxide Alarm to continue enjoying worry-free living for another ten years. Highly recommend this product for anyone looking for a reliable and user-friendly carbon monoxide alarm!

Title: Works Well, But Read the Fine Print!
Review: Attractive; Easy to Activate; Detects and Alarms Appropriately. I always read the 1 star reviews before buying a product. Some disturbing comments were: “batteries are impossible to insert” — I had no trouble inserting the batteries (fit firmly but install with gentle pressure); “Tested with CO and got NO Audible Alarm” — this was a big red flag, so I tested my unit upon activation. At 500+ ppm CO got good LED visible readout, but NO audible alarm. Was ready to repackage and return, but re-read the product information sheet: “This alarm measures the exposure to carbon monoxide over time; it is designed to sound at 85 decibels at 10 feet when it detects 70 ppm (parts per million) of CO for 60 to 240 minutes, 150 ppm for 10 to 50 minutes, or 400 ppm for 4 to 15 minutes.” I retested, exposing unit to 400-650 ppm CO and got an audible alarm at around 6 minutes. Removal from source, display returned to zero and audible alarm ceased. Much more assured that the unit works properly. And Audible Alarm times are well within guidelines for exposure to CO and symptom development (see photo). Also really like that I can replace batteries. Previous units with sealed batteries didn’t last anywhere near the 10 year “useable life” advertised.

Title: I have compared 3 different detectors in this review
Review: I am comparing 3 detectors for your shopping convenience. The Aegis EC50, Kidde KN-COPP-B-LPM and the X-Sense CO05S. Aegis did not come with any battery, may it did for the one reviewer because there are 2 AA slots where the batteries go on the package and they are empty. I think the factory tried later to save the cost of the batteries. I had to dig in my storage bins for some spares. It took two AA 2850×2=5700mAh and the battery door was extremely difficult to open at the back. The instruction was not clear on where the door separates (bad picture) and it turned out, the battery door was the entire super thin circular plate with nothing you can grab on and it looked like part of the plastic casing. I had to dig my 2 fingers into the two tiny openings of the plate to turn it and they kept on slipping. I am mechanically inclined and had opened every battery door of every product I have purchased without instruction but I had to fight to open this one. If you just look at the way the battery door was designed, you know this product was not well thought out. The LCD fogged up when I was doing the test behind my car’s exhaust pipe and I could barely see the screen so I could not continue my carbon monoxide test. I tested the Kidde KN-COPP-B-LPM the same way and the alarm took forever to come on about 7 and half minutes. It came with 3 AA batteries 2850mAh x 3=8550mAh and they should last. The other detector tested was the X-Sense CO05S which came with one 9V battery 625mm AAAA x 6=3750mAh (9V battery is compose of 4 AAAA each has the capacity of 625mAh) which I know it is not going to last as long as the Kidde and the Aegis , even with the power saving circuit. However the X-Sense had a faster detection time as it only took 6 minutes for the alarm to trigger, about one and half minutes earlier than the Kidde. Unfortunately the alarm was only half as loud as the Kidde. I would say if you close the bedroom door, it would be hard to hear it. Out of the 3 detectors, I give the winner to the Kidde and it so happen to be the least expensive. Another benefit of the Kidde is that it is more portable, about half the size of the other two. The only benefit of the X-Sense is that it reacts faster and that 90 seconds faster response may safe life but the problem is that you may not hear the alarm. Hopefully I have saved you some money and headache picking a detector.

Title: Performs as advertised
Review: I originally purchased 2 of these units on 2/18/2015. Yesterday, 3/10/2025, one of the units started chirping every 30 seconds. The display read “END”, meaning that the detector has expired, and will no longer work. The instructions explain that these detectors have a 10 year life span. No complaints here! I am about to order 2 exact replacements, as I expect the second unit to expire soon. I mount one in the basement and one in the hallway outside the master bedroom.I highly recommend this product.

Review: I have had these Kidde products before and they have lasted a very long time before they reach their “end of life.” I purchased this carbon monoxide detector to replace an older Kidde model and so far it has been tested and definitely works, let’s hope it never has to beep that loudly again. I recommend this Kidde carbon monoxide detector because it is battery operated and has a useful LCD screen to show relevant information. Mounting screws and batteries were included along with a manual that you should read as it has placement and function details.

Review: I had an identical one which had the name Garrison on it and it lasted 10 years when it stopped working due to its programming. It gave me no problems so I searched for the same item and I found this one which now has the name Kidde on it. I like the digital display feature.
