Smoke and Carbon Monoxide Detector, 10-Year Battery Powered, LED Status Lights, 85 dB Alarm, 5-inches, 30CUD10, 1 Pack

Purchased in 10/2025. Now after six months, we have had no false alarms. It is mounted in a den near the kitchen and cooking smoke/toast burning has yet to set off a false alarm. It is smaller than prior Kidde models that I have purchased. I hope it continues to perform in this manner with few false alarms. I will update my review if a false alarm occurs. This unit has now doubled in price though.

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!

January20 2026, I’m updating my review to share I called the company and complained about the product and they are sending a replacement. If they don’t work, I don’t plan to buy this brand but thought I’d update that calling KIDDE directly they offered customer service to attempt to fix the issue, hopefully this will be a better experience than my current purchase! Don’t buy these! Save your money! My contractor said this was the best brand to purchase and they didn’t last a year, so many false chirps, I cleaned them, tested/reset them and within 24 hours they again go off with a series of three chirps. I am so disappointed with this product I don’t plan to buy them again! No false chirps is false advertising! Faulty, dysfunctional, and caused much stress for my pets with them going off. I’m a non smoker, no wood heat of any type, and not burning my food, absolutely no reason for them to have continuous chirps of three going off at all. Poor product! This product gets zero stars, only put one so I could post the review!

This is the most recommended smoke/CO2 combo unit. We had them in our previous house, and recently moved. We are switching all the detectors that are in our new home (and they're all new) for these.

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 monoxide Negatives - No bracket standard hole pattern means having to drill new holes and possibly remove old anchors

Installed in January. Is now May. Thought one was chirping. Turns out I have a 4th detector the house. I bought a 3 pack. So far so good.

Everything as promised

Easy to use an entire property I have those I’m very happy with the quantity
