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.

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.

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.

Easy to put together and install. Works well.

my last kidde lasted almost 11 years...

the website was confusing, and when I tried to use the product it didn't work.

Excellent choice! Great price!

Wrong deliveries and the credit is most slowest thing I have seen so far.
