Amazon.com Product Review
Designed for residential use, the Nighthawk Carbon Monoxide detector keeps everyone in the house safe from poisonous, odorless CO fumes. The unit detects carbon monoxide levels from 30 to 999 parts per million. Its low-profile design doesn't stand out when connect to any wall outlet. The unit plugs directly into AC outlets for easy setup, and comes equipped with a 9-volt battery for backup during power outages. Its loud, 85-decibel alarm is sure to alert the whole house when safe carbon monoxide levels are breached. The Nighthawk is UL listed, and features a continuous digital readout of carbon monoxide levels, as well as peak-level memory display, and a test/reset button. It also can be stationed on a tabletop with the included 8-foot AC cord. The Nighthawk comes with a 5-year manufacturer warranty. --Brian D. Olson

 Battery Problem December 30, 2008

This product is a joke, the unit I have drains a new battery in a few hours, and it starts beeping during the night, asking for a new battery. The beep is so loud ...
Removed the battery? sorry, no battery is not an option, it will beep if there is no battery.
What can you do?
Please don't waste your money or energy on a product like this.
 Ordered this to replace my old one... and they a very important December 23, 2008
A little over two years ago the one I am replacing (only because it is over 5 years old) started chirping at about 10 pm. I watched the numbers climb and when it got over 100 (and stood there) I went outside to investgate. Low and behold there was smoke coming from the manhole cover a few doors up from my house. A quick look at the two manholes further down the block and they had even more smoke. You could hear what sounded like a massive electrical short under the street. So bad it was actually vibrating the street. A quick call to Con Ed (Electric Company here in NY) and 911 and emergency services showed up. Evacutated about a dozen houses because they all had detectable CM levels. But only I had a detector. I would have to say it kept dozens of people from getting sick or worse. It is your choice but I will never be without one. If mine did not go off no one might have noticed...
 Carbon Monoxide Plug In Alarm Kidde KN-COPP-3 December 20, 2008
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.

We've had this CO detector plugged in for over six years and the only time it ever sounded an alarm was when we had hardwood floors installed in our house. I'm not sure what triggered the alarm but it got everyone's attention. It's LOUD. There's no way anyone will sleep through this sound. You can hear the alarm outside when it's going off inside. Once the alarm sounds you have to power it off to silence it.
Since it's sort of difficult to tell if a particular CO detector is working properly, we've diversified by having three different models in our house. You should be able to test the Kidde Nighthawk unit (or any other unit with a digital readout) by placing it close to burning material, or next to the exhaust pipe on your car, but we haven't done that. During such a test, the digital readout would change from 0 to some higher number representing the amount of CO in the air in parts-per-million. Any reading around 30 or so means you need to figure out why your unit isn't reading 0, and that while you're not at risk for immediate death you're being subjected to continuous low levels of CO which is not good. Anything around 100 means immediate trouble. About 800 ppm and higher means you're going to die if you don't get things straightened out quickly. Around 12,000 corresponds to death in a minute.
CO detectors are required to be installed in new construction in some areas, and I'm sure that eventually most states will pass similar legislation requiring them.
Our CO detectors give us some peace-of-mind. The ones with the digital displays like this Nighthawk are a little more useful because you can see if they're detecting anything at all. I'd recommend you get a few no matter the make or model, even if they don't have digital displays.
Carbon Monoxide Detector November 22, 2008
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.
