Query: Just had a false gas alarm

We just had an explosive gas alarm tonight. I picked up the baby and ran out of the house into the 27 degree night, the fire dept came out and found nothing wrong. I decided to see if there were any reviews on this unit. I wish I had read the reviews before I bought this. I don't want to throw it out just in case it does detect gas one day, hopefully there won't be any more false alarms. I know gas has a smell, but I used to live in an apt. before where there was a gas leak and I didn't know it, so I'm sort of paranoid now. The fire dept. gave us a new battery so we'll see. Why can't anyone make a reliable gas detector?
