Customer Review: Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm Summary: 5 Stars
As of this writing, all I can say is this unit is plug and go.
Haven't had any of the issues that previous reviewers have had, but that may be due in part to the research I did prior to purchase.
Customer Review: CO alarm Summary: 5 Stars
We have had these CO detectors in our home for years. Bought this one as a gift for our son in his new home.
They do have to be replaced after 7 years (something that's not real clear on the package).
Customer Review: Best in its class Summary: 5 Stars
This Carbon Monoxide Detector was recommended by Tech putting in new furance. Said the First Alert Alarms weren't good @ all! Suggested getting one with 'face'.
Have already told others about it.
Customer Review: Nighthawk plug in carbon monoxide detector Summary: 5 Stars
I regard this device as a first class product. I purchased it to replace its 7 year old counterpart which has failed in the time frame predicted by the owners manual. I am happy and safe with this detector.
