Easy to install, light tells if it is working, good value for price.

this thing woke us up at 2 in the morning... kept going off so we called the fire department. we sat out on our porch for 2 hours talking to a policeman and fire chief while we waited for the gas company and a sherifs deputy to show up with testing equipment! LOUSY machine!!! they couldn't find any problems, but the gas man said to set it outside in the fresh air to reset. Don't you know, started going off again (outside) while we were trying to catch up on our sleep. We've only had the thing for about 2 months. My husband just put it together and mounted it on the wall a few weeks ago, so it should be in tip top shape!

I've used several carbon monoxide alarms from First Alert for the past couple of years. Sadly, I was very dissapointed with the fact that they've shorted out after only a few months. For Kidde, they've made high quality carbon monoxide alarms, but also a very convient prices. The Kidde KN-COBB Basic Carbin Monoxide Alarm is a very simple and easy to setup alarm. This alrm is very affordable, and you can easily hang it up, without any problems. It is also easy to install the batteries, unlike those that require a 9 Volt batteries. Here, all it takes is a trio of AA batteries, and it works better, even during a power outage. Kidde does show it, and I really suggest you have one for your everyday houselhold.

I own this detector for 1 1/2 years before I have to replace batteries. You don't realize how convenient it is to have the battery compartment at the front until you start replacing batteries of the existing smoke and carbon mono detectors in your house. Most of those installed in our house needs 9 volts rectangular batteries which are not easy to find and expensive. This needs 3 regular size "AA" batteries. We also have high ceilings, so I have to use higher stools or ladder to replace them. The battery access is at the back so I need to remove the unit from the ceiling first. It is easy to remove them with a single twist, but once you replace the battery, re-installing them is a nightmare. This unit saves you a lot of frustration and heartaches because you don't have to remove it at all and all you need to do is flip the front battery cover and you are done.

Instruction is attached to the back, so you don't have to worry about losing them. 4 quick beeps signal an alarm condition. Single beep every 30 seconds indicate low battery.

Simple design. Looks good.

We have had three of these units for less than six months. We also have two other CO units that are AC only that we have had for a few years.

Just about every week one of these three units beeps very loudly for three or four beeps and then quits. This is very annoying when you are sleeping. It does not continue like it is a real alarm. They are not the soft chirps indicating low batteries. I have replaced all the batteries with new quality batteries instead of the cheap ones that come with the unit. Our regular, more expensive, CO units have never gone off at the same time as these cheap units. Buy the more expensive units.

We do not think these are unsafe, just annoying.

I have had one of these alarms for a month or so, and last night it started going off while I was making dinner. I took the alarm outside and it stopped beeping, so I decided it was probably real and called 911. They came over and their detectors read absolutely nothing. So while I think a CO detector is an important item in every home, I worry about the accuracy of this one.

I bought this about 3 years ago. Throughout that time it has signaled to change the battery so I've done that a couple of times, the last being about a month ago. Last night at 3:30AM the alarm went off. It was downstairs and I could hear it clearly although at first I thought it was a low battery baby monitor. I called an emergency number that wouldn't go through and being it was so late I then decided to just turn the thermostat down and open a couple of windows. To be honest I was suspicious of the alarm working properly, but glad I at least did that. Later that day I had a heating and cooling repair service inspect my furnace and yes it was sending carbon monoxide throughout the house at a high rate. Bad news is I need to replace my 70's model furnace, but the good news is this alarm could be responsible for saving the lives of my family.

I put this by the pellet stove and it hasnt gone off yet and I have woken up alive every morning.......so it seems to do its job ok.

Easy to install, went up in minutes, came with batteries and clear instructions.

I purchased from this seller because I wanted to replace my old alarm with the same model (the circular one shown in the picture), so that I wouldn't have to worry about moving the mounting screws or anything. The item I received was the newer, rectangular model of this alarm, sold as the 9CO5-LP.

I did have to move a screw, which only took a minute, but I'm more upset that I went out of my way to pay more for the item advertised, as well as paid for shipping instead of using a Prime-eligible seller, and ended up with the same item I could have gotten for over $10 less from another seller.
