🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The product under review functions as expected, with many users praising its reliability and easy installation. Some customers noted that the 9v battery included with the product was dead on arrival, but were generally satisfied with the detector's performance. One customer highlighted that the product's design is standard and not as upscale as previous models.

Pros

  • 👍 Easy to install
  • 👌 Works as intended
  • 😊 Great price
  • ✅ Reliable

Cons

  • 👎 9v battery is often dead on arrival
  • 🙁 Design is not as visually appealing compared to old models
  • 😕 Doesn't mention recyclability
  • 🙈 Short product lifespan

Should I Buy It?

Yes, considering its affordable price, easy installation, and overall functionality, it's a sensible purchase for home safety. However, you should also be prepared to invest in a 9v battery, as the included one is often dead on delivery and be aware that you may need to replace the detector after a few years due to its short lifespan.


  • Work great for a long time
Size: 5.75 diameter x 1.8 depth Pattern Name: Detector
This Carbon Monoxide Detector is a direct replacement for those that were originally installed. It was easy to swap out the old one with this new one. Friends in the local fire department recommend this unit as being reliable.

  • Great CO detector
Size: 5.75 diameter x 1.8 depth Pattern Name: Detector
I was having problems with the hard-wired CO and smoke detectors in my home and was searching for replacements. In doing some online research, I ended up calling Kidde (pronounced kid-ah, I found out), and had a nice, long, informative conversation with a very pleasant lady in customer service. We discussed all the pro's and con's of various units, and these detectors sounded like what I wanted. My existing detectors were First Alert, so in order to install the Kidde detectors without doing some rewiring, I needed to get adapters, which convert the wiring harness plug from First Alert to Kidde. Unfortunately, I could not get these from Amazon. The only adapter they offered was a package of two, one of each type, so you had to use one and throw the other one away. And there was a 2-week wait on those. That was the negative, but price-wise, Amazon couldn't be beat for the detectors, especially since I needed 2 CO detectors and 8 smoke detectors. The switch-over from the old detectors to the Kidde detectors was simple and fast. One thing I found out about the CO detectors is that they have a limited lifespan and need to be replaced every 4-5 years. Mine were 6 years old, which is probably why I had to replace the backup batteries about once a month. I had one that would continue to chirp even with a new battery, which is what prompted the replacement in the first place. I really like these new Kidde CO detectors because they have a digital display, which will show the level of CO if there is an alarm, and they will also show you when the battery needs to be replaced. ... show more

  • Really like this CO detector
Size: 5.75 diameter x 1.8 depth Pattern Name: Detector
Really like this CO detector, it just saved us a few days ago. Every 15 seconds or so (I didn't time it, don't quote me) it take a reading and will actually show you on the display what the CO concentration is. Hopefully it's zero. I didn't know that closing too many vents can cause your furnace not to be able to properly clear exhaust. So I went around shutting vents in rooms we don't use very often. A while later this starts beeping. I thought it was the battery, but then I looked and the readout was 90, it was detecting unsafe levels of CO in the house. Shut the furnace off, opened up the house to air it out, ran the fan to move fresh air around. Looked it up and lack of proper airflow can cause that to happen. So I opened vents back up and it hasn't happened since. None of the older detectors in the house alerted because it wasn't crazy high levels yet, but this one warned me way ahead of time. Well worth it when your little girl is napping. ... show more

  • Kidde Carbon Monoxide Detector Alarm
Size: 5.75 diameter x 1.8 depth Pattern Name: Detector
My previous carbon monoxide detector which is exactly like this came to the end of its performance. The good thing about this detector is the that it flashes a message "END" when it time for it to be replaced. The noise level is very audible so if there is ever any issue you will be sure to hear!! I've had this brand since I purchased my home 15 years ago and this is the second time I've replaced this unit. So, the lifespan is about 7.5 years which I consider to be pretty good!!! ... show more

  • Works well, fairly easy installation
Size: 5.75 diameter x 1.8 depth Pattern Name: Detector
I bought two of these along with seven of the Kidde model PI 2010 smoke alarms as part of an interconnected alarm system I needed to install. To me, the important features were the ability to combine the CO alarms with smoke alarms on a single system, the digital readout (ppm CO), and the 120 volt power with battery backup. The units were easy to install for the most part, as the mounting plate and wiring harness are identical to those supplied with the smoke alarms. They started working immediately and have had no problems so far. Plugging the wiring harness into the back of the alarm was somewhat difficult, and it will need to be unplugged to change the battery. Because of that I'm not looking forward to the annual task of replacing batteries on all nine units, and it leaves me wondering when the designers will come up with an easier type of connection. Other than that I have no complaints, and I would recommend these units for anyone needing a 120 volt powered CO alarm. ... show more
