Ok, from the replies I got, I am pretty sure my video was not clear about how and when to use the toilet vent. A normal bathroom fan is run for maybe 10 minutes after you go number two, to remove the odor hanging in the air. The toilet vent fan is only run for the two minutes, or so, that you are actually sitting on the toilet, going number two, and then you turn it off after you flush. The amazing thing is that ZERO smell gets into the bathroom air. You can literally take a dump, and your wife can walk in the bathroom right after you and not even realize what just happened.
