Good product, has some plusses over earlier model, one downside
on June 1, 2009
Kidde makes good CO detectors. We've had several Nighthawks for years and they've worked well (at least we think so, never had a CO problem). Our previous version was the the COPP-3 (we had a couple of experiences with the low battery chirping-- a nuisance in the middle of the night--and once, it happened again shortly after we had put a new battery in. Others have had many more problems in that regard--see reviews).
It was time to replace them. We first bought 3 Kidde KN-COPP-B Front Load Battery-Operated Carbon Monoxide Alarm with Digital Display--but ran into several problems (see my review). The biggest problem was that Amazon's stock was old (the detectors were over 2 years old) and the warranty was only for 5 years. Other downsides are that they required mounting and were only battery operated! We returned them making use of Amazon's consumer-friendly return policy.
We then bought this model. It has these great features.
1) Comes with a 7-year warranty (new feature, old had 5 years).
2) Shows the CO level continuously. It's reassuring to see the red LED showing 0!
3) Has a well designed, clearly organized printed manual (a small booklet).
4) Operates off of AC with a battery backup. (That's helpful as you have the best of both worlds!)
5) Has peak level button (this is a new feature).
6) Battery included.
A Big Downside:
A big downside is that they eliminated the plug on a cord. That was really helpful as it gives the user real flexibility in where to put the detector. In our bedroom, the only accessible plugs are beside a dresser in a corner or between bookshelves and the TV stand, meaning less air flow. With the old model, you could plug in the device and then with the cord, put the detector on the top of a bookshelf or stand. Much more convenient.
The other problem, which plagues all the CO detectors and many other products on the market, is the infuriating, hard plastic packaging. It's hard to open and I even cut myself on it. There are alternatives that are just as secure but much friendlier to the environment and the customer!
We still have a year or two left on one of our old ones, so we're keeping that. We also bought a First Alert CO615, which does have the cord, and we'll probably move that into our bedroom when the time comes. (But it has more negatives--see review!)
