Query: very disappointing, a waste of money

I decided to buy this book after reading the good reviews, I was looking for a fairly basic book to help me with bicycle maintenance and some easy repairs or adjustments, like how to adjust a rear derailleur, etc. I am very disappointed, the book is filled with technical language, there are a series of photos with little or no legend, which makes it very difficult or impossible to understand and follow the instructions, annotated graphics would have helped a lot instead.if you are a professional and familiar with bike repair, then this book probably makes sense, but then, do you really need this book?otherwise if you are like me, with very limited technical knowledge, you are better off with something more basic and/or better explained with helpful graphics.
