It really works!

6 April 2018 - Published on Amazon.com

Verified Purchase

I bought this 4 years ago. Put it in the walk-in closet where we sometimes put our baby down to sleep in the basement and basically forgot it was there, with the exception of occasionally wondering if it really does work. Well....this week we found out. The alarm went off in the morning, I pushed the reset button to turn it off (I appreciate that there is a different beeping pattern to indicate low battery vs. dangerous carbon monoxide levels) and the alarm didn't resignal, so I kept wondering if it was a fluke or if I should do something about it. Finally, I decided better to play it safe than sorry given that several of my kids had been feeling tired/headaches the past couple days (could've been coincidence) and called the fire department for advice. They came out and sure enough, we had abnormally high levels in the basement. The gas company came out with more sophisticated equipment and pinpointed our furnace--turns out we had a cracked heater exchange that was emitting carbon monoxide. So thankful we had this detector!

Completely useless, failed to detect leaking furnace

28 March 2019 - Published on Amazon.com

Verified Purchase

I bought this unit in the spring of 2017 and installed it in my basement near the furnace. A few days ago (just under two years later), the heat exchanger in the furnace cracked and it started leaking carbon monoxide into the basement and distributing it throughout the house. Two CO/smoke combination detectors that I had on my second floor went off, but this unit remained completely silent. The fire department measured 160 ppm of carbon monoxide in the basement where this unit was located, far higher than what they measured on the second floor. After this incident, the test button on this unit confirmed that the batteries were still good, so I have no idea what the problem was. I'll be replacing this unit with something that hopefully works.

Works!

Seems to work well, as recently I cooked in our propane fueled stove, and after turning off the oven the detector alarm went off. We then realized that we smelled a bit of propane gas. We could have just gone to bed and had it leaking all night long. But the alarm worked.

Simple. Inexpensive.

2 January 2018 - Published on Amazon.com

Verified Purchase

One of my carbon monoxide detectors had reached it's "end of life", so I was looking for a simple, inexpensive, replacement that just does its job. The Kidde KN-COB-B-LPM Carbon Monoxide Alarm fit the bill. It costs under $15. It runs on two AA batteries. And it installs in minutes. The alarm is loud, and its features are very basic. You have a test button and a couple of LEDs to show the alarm's status. That's it. If you're looking for a fancy detector loaded with features, this isn't it. If you want simplicity and low cost, this detector will do the job.

These detectors have a hard life of 10 years. At 10 years, they start complaining, loudly, and need to be replaced quickly. This is unfortunately very frustrating if you are a landlord and have a lot of units. Because like a virus, every one of your tenants start going insane when this starts beeping. And unless you kept careful records of which unit got which alarm when (which I clearly didn't), you will find yourself replacing these every single week as each one conks out unexpectedly, usually during the night and in at least 20% of the cases, when a tenant was away on vacation so the adjoining tenants woke me up to deal with it.

If your unit is going to start failing, have it flash a little bit or behave oddly for a month or two before it starts beeping every 30 seconds. At least there's a chance that the tenant will let you know something is starting to go with the CO detector.

And FWIW, I have no idea if this actually detects. The only time these go off is when the batteries need to be replaced OR we hit the 10 year mark.
