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

I bought three of these for our Airbnb 18 months ago. Today we found one of them screaming at the top of his lungs. Neither the alarm clock nor the fault lamp does not respond to the reset button. I removed it from the wall mount, which unnecessarily requires you to stick a small screwdriver in the slot. I opened the device and turned it off (there is a switch inside). I stood outside for 2 hours and when I turned it back on it started screaming again. It would be a disaster if it didn't work out when we had guests. Now I have to replace all three - I can't make another one of them scream.
