Query: It's ok for beginners

I only bought this book for the 9-ball section and was left a little disappointed. The book is aimed more at begineers so in that respect it is OK. I found that some of the diagrams did not really match the shot suggested and there was one mistake on page 106. That said this book is cheap and if you don't just play 9-ball then it could be worth the investment.
