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.

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

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.
