Happy camper-Kidde Smoke/Carbon Monoxide Detector
This is the second set of two Kidde Smoke %26 Carbon Monoxide Detectors that I have purchased. The first set lasted trouble free for approx. 10 years so I have good reason to expect that these new ones will do just as well. I didn't even have to change the mounting plates as these newer ones are exactly the same making the installation a virtually a nothing burger. Walmart's delivery was prompt too. I'm a happy camper.

Review of Kidde CO Smoke Alarm
Our old Kidde CO Smoke Alarm system failed due to age. I ordered it through the Walmart Website. One advantage of ordering the same manufacturer is that the new one easily screwed into the plate on our ceiling from the old one.

APPEARS TO BE A GOOD PRODUCT FOR A GOOD PRICE
We have only had the product for a couple of weeks and it appears to be doing great. We also like the fact that it is a carbon monoxide detector as well as a smoke detector. t
