I seriously believe that most of the 5 star reviews here were written by people who have not actually tried to use this book.It's an interesting concept, but the book is chock full of errors and mostly useless, though I will say that the author thinks exceedingly highly of himself without having a lot to back it up. At least not in this book. It's almost as thought some of the translations are direct from babelfish because they're sort of close, but laughably off in many cases.If you seriously attempt to use this book, prepare to be the life of the party, because you will be a hoot--of course, the laughs will be on you.
