I bought this book a few months ago. My big problem with the book is the binding. It's perfect binding so the pages are glued to the cover. The first copy of the book I bought, the pages completely separated from the cover, and the book was about to fall apart after one week of light use. I returned the book to get a new, less defective copy, but the new copy also had defective binding. I don't know if all the books have that problem, but it's something to be aware of.
