While the *visual* demonstration of the various stances in this DVD is fairly clear, Kancho Hirokazu's broken English makes it nearly impossible to understand what he is saying or what the names of the techniques are. As instructional material, it is very poor, since one can't understand what he is saying. I have seen other karate DVDs where a fluent English voice explains what the particular sensei in those DVDs is saying (e.g. "functional karate"). I don't recommend this DVD.
