super easy to install, no wires and if the built in battery last 10 years like they claim with no chirping, well worth the money

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.

was very excited to not have to worry about batteries in a smoke detector and its also a carbon monoxide detector. however the smoke alarm randomly goes off with no smoke or heat anywhere, usually its like 3 a.m when it does it. very aggravating, i think ill go back to classic battery smoke detector.

Kidde is an excellent smoke and CO detector, and I have always used this brand. Reason for buying a new detector is because my old detector requiring yearly battery replacement stopped working. So, I this new detector with a 10 year battery life. Reason for giving it a 4 star rating instead of 5, is because the base is smaller than my old detector and I had to drill new holes in my wall position it to cover the old holes.

This combination smoke/carbon monoxide detector is absolute garbage! I have bought all types of kidde product's as a owner/landlord of multiple home's. I opted for the 10 yr lithium so, I didn't have to worry about replacing battery's or missing unit's in general. I took the first one out of the package, test, reset %26 the dang thing wouldn't stop going off! I eventually had to wrap in a towel, placed in a safe and threw the dang thing in my trunk! Two days later it finally expired %26 will be returning all 6 unit's! So much for a 10 yr lithium battery huh!? I suggest buying individual one's as my intuition was right %26 you can place the carbon monoxide one closer to floor level. Save your time and money. Kidde do Better!! You have our families precious life's relying on being alerted to a emergency.

I bought this in Spring of 2025, and here I sit in December with it chirping randomly. No matter how many times I reset it or try to stop it, it continues to chirp randomly throughout the week. And I can't get it off the wall. So today, I am ready to smash it with a hammer and replaster... that's how crazy I am from the chirping of this garbage alarm. You too, can have this experience... just buy one of these "10-year battery" alarms! But I'd pass, if I were you. UPDATE: E-mail response was to replace the battery. Ummm... that's the reason I bought the 10-yr and they're not supposed to be replaced anyway, sooo... maybe that's someone new? Anyway, I called, and the nice gentleman on the phone says they're sending me a replacement. So I will enthrall you with my updates if anything goes wrong with the alarm in the next few months. We'll see!

I appreciate that I do not have to be concerned once a year to check battery.

Easy to hang up on the wall. I hope we never need to use it but if we do it will save our lives!
