I didn't look at any of the Videos Norm ,I just can't see the point of making a fan that gives you carbon monoxide poisoning .
It always surprises me the amount of people that go out and get a generator when the power goes out ,then they run the generator
too close to the house when a door or window is open and they don't last long.
