Norm: It seems to work (how would you know?), Bright display but also quite large and heavy. Better have a pretty tight socket to plug it into.

Lance McGrew: The life expectancy of this alarm begins upon the initial power up of the unit. The date of manufacture can be within a year or 2 from the current date when purchasing. If you go ahead and power up the alarm, you should get the full life from the unit.

The 10-year warranty through Kidde starts on the date of purchase. We recommend that you keep your receipt in case needed for any reason.

Thom17043: This replaces an identical unit that I had been using for many years. The previous one started giving errors, so it was simple enough to just replace it with the same unit again.

DJ: Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display is a wonderful product. I had one in my new house when I brought it. But I decided to get another on a different floor just as a back up. The unit works perfectly well. There is one complaint that I have, when plugged into the outlet, it tends to come loose very easily. But since it comes with the 9V battery, I was not worried. I did get a few false alarms in the beginning but it has not been case for the past few months. Overall, I am very happy with the product. It does what is supposed to do. I had decided to buy the unit after doing very extensive review of the detectors and this one seems to get the best reviews. I would recommend this to anyone. Below is the breakdown of various descriptions and features.
