Bought this book last month, and it isn't worth the cost of the paper it was printed on! As one would expect, the table of contents lists topics and page numbers......... except none of the pages in the book are numbered!
The missing words, space gaps, punctuation errors, words that don't belong, etc. were so distracting that I couldn't focus on the content (which was poorly written anyway). Clearly, there was no editing by the author or publisher before printing this book. Mistakes like printing "Monday focus" instead of "Manual Focus". On one page, he says "An exhausted battery will fully charge in about two hours and 35 minutes". On the next page, he says "A fully drained battery will take about one hour and fifty minutes to charge completely".
Bottom line, pay a little more and buy a credible book that explains features more clearly and has passed through the hands of an editor!
