Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
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: Better than First Alert
Summary: 5 Stars
This is much better that the similiar model from First Alert. The Kidde KN-COPP-3 Nighthawk has two major advantages as compared to the First Alert model. The Kidder has a red digital display which is much easier to read than the First Alert model which is black on a gray background which is hard to read at certain angles. When the power goes out in my home, the Kidde continues to show the digital readout of CO by using the battery power, the First Alert model digital display does not record the CO level, instead it show that the battery power is being used. I have replace all 4 of my First Alerts in my home with the Kiddd CO detectors.Customer Review: Burns thru batteries even when plugged in
Summary: 1 Stars
Be prepared to have to replace the 9-volt every 4-6 weeks. Burns thru the battery even when plugged inCustomer Review: CO Detector
Summary: 4 Stars
This detector is easy to set up and use. Lets you clearly know when the battery is getting low, although the signal might be a little too loud for some. Warranteed for 5 years, and normally lasts that long, but not that much longer (i.e., not 10 years, but probably 7), before it needs to be replaced. I use one for every level in my home...it's worth it, believe me. CO can overtake you without your even knowing it, so it's a necessary item for every home.Customer Review: CO Detector False Alarms
Summary: 5 Stars
I have had this detector for a few years and it has worked flawlessly. I have always had very low CO readings in my house since it is 75 years old now. Recently, my wife while in the house, was talking on her Cellular Phone, and walked within 5 feet of this detector, and it set off the detector and caused the detector to generate false readings from the radiation that the Cell Phone was producing. She actually saw the display, displaying a series of random numbers, as she was talking on her cellular phone. We also have 900MHz cordless phones in the house and these do not appear to affect the detector.
