I recently purchased the Kidde 900-CUAR-V Carbon Monoxide Detector, and it has been a great addition to my home safety setup. Here's why I highly recommend it:**Pros:**- **Accurate and Reliable:** The digital display provides real-time CO readings, which is reassuring. It’s sensitive and alerts at the right time without false alarms.- **Easy Installation:** The instructions are clear, and it took me just a few minutes to set it up.- **Battery Backup:** It has a built-in battery backup, so it works even during power outages—a must-have feature.- **Compact Design:** It’s unobtrusive and blends well with home decor.- **UL-Certified:** This adds extra peace of mind knowing it meets high safety standards.**Cons:**- The alarm sound is very loud, which is great for safety but might be startling.Overall, the Kidde 900-CUAR-V is an excellent product that prioritizes safety and ease of use. I feel much more secure knowing my family is protected from the dangers of carbon monoxide. Highly recommend it!

I have a whole wired house of smoke detectors. My model was discontinude, but after checking the Kidde website, these are the exact new replacements for my system. Simple and easy to replace existing wire harness and install the new ones. These are working perfect.

Check your equipment, your life depends on it!

So I get it, when the next design comes out (old units are 10 yrs old and it's time for replacement) things change right? Most likely from year to year. But does the design really need to change so much that the leads for the AC supply have to change as well?Has anyone at Kidde thought that with multiple detectors ,a home owner has to go through the process of determining which circuit breaker feeds each alarm. This turns a simple job into a larger project. As a retired maintenance guy I have the tools to perform this task easily enough. While others may have to hire the job out.OK rant over. Kidde makes an excellent product that functions well.

I had two of the older designed Kidde Hardwired Smoke & Carbon Monoxide Detectors. They were wired together with five Kidde hardwired Smoke Detectors. The detectors were 7 - 8 years old. On a regular basis, I would get false alarms--usually in the middle of the night for no reason. With regular back-up battery changes, I was getting chirping and false alarms. Being frustrated, I replaced all the alarms with the same Kidde brand. The smoke detectors were a retro fit--plug and play. The new designed Kidde Hardwired Smoke & Carbon Monoxide Detectors fit on the same mount, but required changing the electrical harness. This wasn't a big deal, turn off the power and match the three wire colors with a twist connector. Delighted to report, that all the alarms are working perfectly. No false alarms and no chirping. Very pleased with the purchase, but am hoping that these last longer than the last set. Time will tell. Saved a ton of money not having to hire an electrician.

I had to replace the “Primary Detector” from a Kidde 4 alarm set that was installed 11 + years ago. When doing the Kidde model number search on Amazon, this was the top of the search. I am glad it was since the secondary or linked bedroom alarms also showed up in the search. So I made a lucky decision on the right model, as this one was ~3 times the cost of the others. It was easy to install as all I had to do was replace the connection plug as it was a slightly different plug style but the prongs were exactly the same line up and this unit linked up perfectly to the bedroom alarms. I did pick up a First Alert 2 pack from Costco, but the prong set up was different, so I did not want to install those as I was not sure they would connect to the others right. Kidde replacement works great.

I'm giving this product a 1 star because it was 100% defective. When I received the item, I noticed that the label that sealed the box closed was cut/torn. I installed the unit with no issues, however, I noticed that every few months, it's actually pretty random, the detector would go off randomly causing all the other alarms to go off as well. This happened throughout 2024 and into 2025 until I removed the unit about a month and a half ago.I didn't know is this unit was the root cause until about a month and a half ago. That's why I decided to just throw it away and buy a new one from a local store.I think what's happening with Amazon, is that they require stores to have liberal return policies which is causing the stores to lose quite a bit of money. So that's why they're sending out returned items as new items. I believe my item that I received was a returned item...but they went ahead and sent it out as a new item. Everything was still in the box and it looked new, just the tape seal was opened.

When our detectors started complaining they were at the end of their life (10 years), I started looking for replacements.Amazon was by far the best priced place to buy them.However . . . . beware, seems as ALL "new" detectors have a different connector for the hardwired units than was in use 10-15 years ago. And no way to make the old connector work on the new as the shape and pin layout is different, so, you'll need to shut off the breaker and swap out the included connector for the old one.
