Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital DisplayCustomer Review: Carbon Monoxide Detector Summary: 4 Stars
Of course there is no way to know if the product will actually detect Carbon Monoxide until there was actually a leak. The product itself lit right up, is clean and not unattractive. I feel better having in my Shop which is right next to a Large Mechanical room housing gas fired boilers.
Customer Review: Carbon Monoxide Plug In Alarm Kidde KN-COPP-3 Summary: 5 Stars
A good quality product, it was purchased as a replacement for a old Kidde plug in which had stopped working after a few years. The main advantage of this newer model unit is the battery backup feature which my older unit did not have. Digital readout and flawless performance make this my choice for a reliable plug in carbon monoxide alarm unit.
Customer Review: Constant false alarm and battery warning beeps Summary: 2 Stars
After about a year or so, the thing started to beep for no reason once in a while. It doesn't do it all the time... just about once or twice a day. The display would read "LB" (low battery) even though the battery was just put in a few hours before.
Customer Review: Consumer Reports Best Buy Summary: 4 Stars
You have the choice of battery or plug-in. I thought I would just forget about the battery but it will alarm until you put one in. I called Kidde and they said they have a different model that would better suit my preference.
Customer Review: Convenient Installation Summary: 4 Stars
Easy to install. Good installation instructions. It's sitting on a bedrooms night table casting a reassuring glow. Too bad it had to be made in China.
