Title: Does it work?
Review: Despite the other reviews describing situations where this detector might have even been life-saving, I am not convinced that the detector I received actually worked. I never saw my detector register anything other than zero, even during an incident in which we lit a wood fire in an indoor fireplace and forgot to open the flue. The apartment quickly filled with smoke, and doubtlessly abundant carbon monoxide from the smoldering wood, and yet the detector steadfastly registered 0 and didn't make a peep.
Is the review positive or negative?
