Install was simple Batteries were included

[This review was collected as part of a promotion.] Easy instructions, I like the convenience of not having to replace the battery

[This review was collected as part of a promotion.] Kidde makes quality products at reasonable prices, and Walmart had them.

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.

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.

Installed on 1/20/2025. On Oct 3, 2025 the smoke detector started going off every few minutes. Nothing was wrong. Could not get the alarm to stop going off, even after rotating slotted arrow. Placed it outside and the dogs didn't appreciate it, so my husband took a hammer to it. We have another smoke detector to put our bedroom hallway, but every time we put it up it goes off. Kidde does not answer their phones.

I bought the alarm an installed it in February this year. No problems until this week, when it suddenly starts going off for 3-5 seconds in the middle of the night. By the time I get up and get to it, it's stopped beeping. I press "reset" -- it does its "green" flashes every 60s to say it's ok, but then 1/2 hour later, it does the same thing. Interrupted sleep for two nights. Checked online and there are tons of people who experience the same problem. Sounds like Kidde alarms are a dud for many, many folks

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.

I bought a four pack in May of this year. I installed three. It is now September, and I have to replace two of them because they won't stop beeping and there is no way to disconnect anything or fix anything or stop it other than discharge it and throw it in the trash which is what I should have done when I bought them.
