Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
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: Smart
Summary: 4 Stars
A very smart CO detector. It's programmed to be unannoying and really does it's homework before an alert, and then it seems to help the residents work through the problem without panic. The draw back is that in 7 years after first powerup the unit churps constantly to get you to "upgrade" to the latest technology by buying a new model. At this price they could have let us use it for 12 years instead of 7. I have two of them and neither has detected the lowest level of 11ppm. It begins to display on LED at 30ppm up to 999ppm. My place gets plenty of natural gas from 3 gigantic water heaters, but no CO. Glad I bought them.Customer Review: Strong Warranty Support
Summary: 5 Stars
This detector looks good, I suppose it works, and it's simple to use. Just install the included 9 volt battery and plug it in.
It has a 5 year warranty and mine broke within a couple of weeks of my 5 year mark. I called Customer Service, they were nice and efficient, they didn't hassle me, and they sent me a new unit in less than a week.
If you don't want to worry about changing out the 9 volt battery periodically, buy a lithium 9 volt battery from CheapBatteries.com. It costs about 4 times as much as an alkaline, but it'll last you 10 years. They're good for smoke detectors too.
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.Customer Review: Try reaching customer service at Kidde (!!)
Summary: 1 Stars
I have had all the problems other users have had with this product. Backup battery drained in 90 days, then 60 days, and alarms went off continuously.
So I called Kidde (Mebane, NC, about an hour away from me) at their 800 number. I called five times, each time waiting on hold for 10 minutes before their line went "dead" and no "on hold" recording returned. I tried reaching technical support, customer service, even sales support. This is on a Tuesday morning at 10:00 a.m. Nothing. I never heard a live human being.
Do NOT buy Kidde products. Waste of money and time.
