Tools and Hardware Reviews of Kidde KN-COPP-3 Nighthawk Plug-In Carbon Monoxide Alarm with Battery Backup and Digital Display
Customer Review: Kidde KN-COPP-3
Summary: 3 Stars
There's a confusing warning in the instruction leaflet saying it wasn't tested for detection of CO levels below 70 ppm. In fact it's very sensitive: I found the peak level registers (typically 10 ppm) if just one burner on a gas range runs for about 15 minutes - the alarm is in a different room.
...only the fact that the alarm is unusable without a battery is a serious drawback. I would have given it 5 stars if it ran off AC only without the useless battery backup feature or if the same company made a detector without the battery backup but still having a digital readout.
Customer Review: Looks nice, but eats batteries every 1-2 months...
Summary: 1 Stars
I own two of these CO2 detectors, and after having both for just over 6 months, I'd recommend looking elsewhere.
I have already replaced the batteries on both 3-4 times, and that is without any power outages in that time. According to the manual, the battery is a backup and is only used when there is a power outage. This is not true... If the unit won't function without a charged battery installed, it's being used all the time.
In my case, this has been an expensive lesson to learn that Nighthawk / Kidde products aren't as good as they used to be.
Customer Review: Eats batteries like it's starving
Summary: 1 Stars
I bought this unit because we have a fireplace. While the unit appears to work detecting carbon monoxide, as another reviewer noted it drains batteries like no tomorrow. The battery in this unit is certainly NOT used for backup. We just went through a 4 day power outage and the unit drained batteries every 4 to 6 hours. We had to keep replacing them as we were using our fireplace as our only meager source of heat. Even with AC power the battery still only lasts for maybe a month. I'm very disappointed in this model, especially since I paid good money for it.
Customer Review: Works....for about 2 years
Summary: 2 Stars
I have purchased three of these (one a replacement) and they appear to work fine. Assuming it works(?) the actual numeric display of the level of CO in the air is reassuring (removes the "well, no alarm, so I guess it's working" doubts). My only issue has been with the product lifespan. Two units worked for only about two years, then displayed error messages which indicate the units had to be replaced. They're not exactly cheap, so replacement is expensive. After 5 years, I would expect to have problems; malfunctions after 2 years...something's not quite right.Customer Review: Does not seem to work
Summary: 1 Stars
I have had one of these (Kiddie Nighthawk) for several years. It always displays 0. A few days ago I decided to test it by turning on a gas burner and holding it about 1.5 feet above it with the stove vent off. After 5 minutes it still showed 0. I left it on my stove while I proceeded to cook dinner with the stove vent still off. Still no change. If this item does not work, it is giving people a false sense of security, and will not protect them. I had a Cousin die and her daughter almost die from carbon-monoxide poisioning (they did not have a detector).
