After seeing this dvd I have to say it was a waste of time.Wacking a steet thug with your car keys will NOT stop him or even really harm him. It will only get them mad and really want to kill you.If any of this nonsense really worked then you might as well carry an umbrella and that would be a better street combat weapon!This tape clearly show everyone one thing, ANYONE can make a self-defense dvd. Save your money and look for something that really teaches prtactical self-defense.
