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.

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.

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.

Activation difficulty

Directions not clear for men who tried to install. I wasted 115.00 because they deactivated and could not be reactivated.

DO NOT BUY THIS PRODUCT…Fails after 6m-12m

After just over one year it has failed and gone into a fatal fault mode, and despite pressing the button on the front after one hour, it falls back into the fault mode and continues on. I immediately read reviews on this product via this website and emailed the email provided by other customers with the same issue with pictures of the front and back and after two days of listening to this go off, I finally had to deactivate the device which some say voids the warranty, but the manufacturer has failed to respond adequately to my email and I cannot continue listening to this beep several times throughout the day. I will not purchase this product again and look at other brands

Unsatisfactory, defective product.

I just purchased this home 2 years ago and I think I have a defective smoke and carbon monoxide alarm, why, it’s to soon for this to give me a problem.
