There were two major problems with this video. First, as a martial arts practioner, many of the items outlined were very much impractical. Second, the video itself was not a professional production; it looks as if it was shot on a home video camera. Personally, I would not waste my time on this video. If you are looking for practical self-defense, I strongly encourage you to look at tapes dealing with Akido, Jujitsu, or Hapkido.
