I just received this from Amazon, at a sale price, so I thought I would clarify what Amazon is selling here. This is the Kidde model number number KN-COPP-B, which is shared by several "assembly numbers" of which this is 900-0089. I think that is what's in the fine print in the photo of the back, but it's hard to read. There are slight cosmetic differences between the pictures and what I received, but less than with other Amazon listings of COPP-B with other assembly numbers.

The important thing is that, although this assembly number has been in use for many years (Google it), the guts of this are the newer technology with the seven year lifespan and death chirp alert, according to what's printed on the case. The case has a handy little summary of what to do for various ranges of alarm readings, so you don't call 911 for minor things, and since you'll never find the manual, which you can read at [...] , albeit for another COPP-B assembly number.

My past carbon monoxide detectors had to be plugged into the wall. And, since CO detectors are best placed high off the floor, this necessitated both close proximity to an outlet and exposure of a wire leading up the wall to the detector. Not a pretty picture.

The placement of the basement CO detector was another problem. There is only one electrical outlet available and the sump pump is plugged into it. Although that left one outlet space free, the design of many CO detectors, requires plugging the entire detector into the space, so the entire outlet plate is blocked. That simply wasn't an option, and since the furnace is located in the basement, it is a location I felt necessitated a detector.

I appreciate being able to precisely place this monitor between my gas fireplace and gas stove without concern for electrical outlet locations. Additionally, I can place it so it isn't obvious. And, the lack of an outlet in the basement became a non-issue with this detector. After reading hundreds of reviews (yes, I did) this model seemed to have the best reliability with the least false alarms, which is a pretty serious consideration given an alarm may require a visit from the fire department. I will update this review if I encounter any problems or phantom alarms, but if I haven't added anything, I am still delighted.

We have had this CO Alarm in our home for years. I am happy to say we have not had it go off.
My neighbor is a fire fighter and told me the digital display is a must and the only thing he has in his home. This is easy to mount and the display is easy to read.
Good CO Alarm.

Having true battery power is nicer than the plug in versions that always seem to need new batteries. After 6 weeks of service, the battery level has lost 1 bar. At that rate, battery changes will be 2xs a year. When the battery does need changing, I plan on putting it outside to air for a day or two as recommended by the fire department.

I am very happy with the ability to place on a countertop and easily check the co measurements.

bought a second one of these to give to a recent graduate. first one has worked flawlessly and has great battery life. the batteries in the new unit had leaked in the packaging forcing me to open up and clean the package before putting in fresh USA made Duracell batteries and reseal.

Note to Kidde: if you can't send good batteries, don't send any.

Only thing I don't like about this monitor is that green LED operation indicating light flashes and it become bothersome when you are trying to sleep. If it wasn't the light I would give 5 stars

We have had one of these for several years. This is a second unit for another room and as a backup. More expensive than other units but very few false alarms by comparison. Plus, if it does go off, you have a digital reading to check to verify what is actually happening. Easy battery change. Instructions are built in to one of the extending wings. Great design.

If you do not have at least one carbon monoxide detector in your house, order this now. It will be one of the cheapest sources of insurance, and peace of mind, you have ever purchased.

I bought this alarm when our son was born and I keep it in the hallway outside of his room. It was very easy to hang on the wall. Our neighbors had to have the fire department come to their house because of a Carbon Monoxide leak in their furnace. Thankfully our alarm has never gone off.

Good - Easy to use. Simple Instructions. Does its job
Suggested Improvements - Color faceplate to match the décor

VERY PLEASED WITH MY PURCHASE, THE ONLY THING WAS, ONE OF THE BATTERIES WAS DEAD. EVERY THING ELSE WAS FINE.
