I've used these for years. I keep one under a seat in the car. Another in the bathroom. Stick one in a closet if it isn't used much and tends to smell musty. They work great.
THE product seems to let off a gaseous odor a few hours after I leave it open. It does not agree with my system as far as breathing is concerned. However, I can only speak for my self.
