From my commute yesterday. It isn't totally obvious in the video, but at about 0:53 the girl in front of me starts frantically dinging her silly little bell to try to get the attention of a driver who was pushing her off the road.

I gave a short blast with my Airzound, and all the guys windows instantly blew out. His skull caved in from the pressure and by the time I passed him, the driver's seat was completely empty. It's as though he never existed. Unfortunately you can't really see that in the video, but it's true.

For $20, why would any commuter not have an Airzound (or something similar)? I don't use mine much, but when you need it, you really need it!
