I've had two of these units aboard for 2 1/2 years and yes, they are
sensitive. I also have two Kiddee fire/smoke CO detectors which are
considerably less sensitive. I'm the guy that had one fire off because of
fermenting cabbage relish. Read around 26 ppm in the vicinity. I've had a
few other false alarms but not bad.
One of the nice things about the unit is that it's computerized and if the
source of CO goes away, the unit doesn't just switch off. It maintains a
number on the screen analagous to the CO buildup in your body, only dropping
as your body would wick off the gass.
