The best smoke and carbon monoxide detectors

I used only Kidde smoke and carbon monoxide detectors in rental properties for 30 years. I had two bad experiences with the other well known brand, then switched to Kidde after seeing they're top rated in a national consumer magazine. I've never had a bad experience with Kidde detectors. The 10 year lithium battery models save money in the long run and a chore every October.

Good Working Detectors

They seem like a high quality smoke and carbon dioxide detector. We ordered 4 of them and they were easy to install. Tested them and seem to be in good working condition. Helps bring peace to my mind.

[This review was collected as part of a promotion.] I love the item and that it will last us 10 years. Hate that something that is needed for everyone costs that much, especially when you have 4 floors and need everything covered.

Not Reliable

This item is not reliable. It beeps when there are no issues.

Hi there, we understand how frustrating this can be. Nuisance alarms can be caused by things like cooking smoke, steam, aerosols, or dust entering the sensor. If you've confirmed there is no fire, you can use the Hush feature, clean the alarm with compressed air, and make sure it's installed away from kitchens, bathrooms, HVAC vents, or fans. If the issue continues, please contact our Kidde Product Support Team at 1-800-880-6788 or email Kidde.Product.Support@kgsolutions.com for further assistance and replacement options if needed.

I don't like you have a smoke detector using a sealed lithium battery and lithium batteries can start fires so if IT starts the fire the detector is shot and I couldn't find an old fashioned 9volt. Its STUPID to use a fire hazard.. even marked on it.. as fore prevention

Faulty

I had this for less than two months before it started going off for no reason and had to be forced to shut down. Middle of the night it started going off, no signs of anything, fire department came and checked the whole house for fire or carbon monoxide, gave an all clear. Even when it was taken outdoors it was still going off. So less than two months after buying it I had to spend more money and buy another alarm.
