As a bilingual (Spanish/English) teacher trying to learn German, I really like this text. I wrote a review of the Arbeitsbuch (Menschen Heir) that accompanies this text, and as I state in that review, the approach is different than the traditional language texts that emphasize travel phrases; they focus on language that would be useful in the work world. Also the book is completely in German, and I really like the immersion approach.
The copies of the book I had included the CDs, but the software did not work very well on my PC. There are additional exercises on line to supplement the text, and they vary in difficulty.
I rated this at four stars because it is not perfect, but as I said in the Arbeitsbuch, the work in the text seems simple but is more challenging to do that it appears.
