Compact, lightweight, easy to carry and inexpensive. That is where the qualities of this product. I bought it to teach me the guitar as a real beginner and I got after the first lessons, flooded with nowhere explained technical terms, tablatures too quickly complicated and a terrible lack of illustrations. The book is not at all didactic and clearly aimed at an audience of insiders who can get by despite the wobbly pedagogy of the author. Avoid if you are a true beginner guitar and music in general.
