Query: False Alarms Galore!

My wife and I bought one of these Kidde Nighthawk alarms and it has alerted us a total of FIVE TIMES WITHIN THE PAST THREE MONTHS that there was explosive gas present with a measurement around 215. Not once has there actually been any sort of a danger. We've had nothing but false alarms with this product, and today, after it going off three consecutive times within the past fifteen minutes, it's getting the boot.The other reviewers are correct in saying that explosive gas has a distinct smell. The only thing *I* was smelling when this alarm went off was the soap I had just used to wash my hands. Deadly and explosive? I think not!
