Query: Poor content, poor technique ...

I'm sorry but I don't recommend this product to anyone.Pros: NONECons:-Poor content and poor presentation, you can't understand what are the basic strokes and what are the basic rhythms clearly. Rolls, slaps, muted strokes are not covered.-Sometimes explanations are very boring.-The instructor seems very uncomfortable.-Long performances, this has to be an instruction material not a performance record.-Poor technique, the instructor's hands are a bit clumsy.
