On the other hand, the book is full of repetition, using the exact same words over and over again. This makes it hard to not fall asleep at some point.

What disturbed me most however, is that the book is full of coding errors. Most sample code doesn't work. Often it will not even compile, because of some syntactic error. I'm smart enough to fix those errors myself, but that doesn't mean that it's okay. I used to think all O'Reilly books were excellent because they were published by O'Reilly. After reading this book, I'm sorry to say this is no longer true.
