As a native German, I'm teaching German with this book for the second year at the University level. Neither me nor my students like this book - in fact, I consider it quite bad (I have taught with 3-4 other textbooks before, any of which was much better) : The "approach" is totally scattered, it tries to be so hip, while it's rather gimmicky with all its cute pictures and cartoons. Like a "lets get away from grammar"-kind of badge of honor, the book introduces a minimum of grammer, but in a confusing, incomplete, and at times faulty manner while expecting the student to "know" or understand lots of things that were never properly introduced. The students would be helpless without a teacher to untangle the mess for them. Also, the reading sections and vocabulary are rather inappropriate, containing words that are neither widely used nor easy to pronounce. This book hinders more than it helps the process of learning German in an enjoyable manner. I only use it to a bare minimum, just to stay on course with the units it introduces.
