I picked this book up from Smashwords with a free coupon yesterday. Regardless of receiving a free copy, these are my honest thoughts and it's just my opinion.
I'm not particularly good with languages. I can actually imagine myself making most of these mistakes if I were to learn (and speak) German to people. I was commenting about this book to my sister, reading the occassional phrase to her, and she made the same comment as well. Though I don't particularly understand all of the points, I found most of them amusing and laughed out loud to many of them. It's a great compilation with a lot of varying words and situations. I quite enjoyed it.
