Review on Enhanced Kidde Worry-Free Carbon Monoxide Detector Alarm: 10 Year Sealed Battery, Model C3010 with Improved SEO by Robert Johnson

It would be very difficult to know if this detector would work or not. but it shows it works and I didn't die of carbon monoxide poisoning so I believe it works. The fact that the battery lasts 10 years and I don't have to deal with pesky alarm clocks in the middle of the night to change the battery is very nice to have. I glance at it from time to time to see the little blinking LED showing it's still on. after months and months. still blinking.
