This is good if you need additional practice and are already familiar with the language as an advanced beginner. It lists key basic words and sentences that are good to know as a crash course to get by. You'll need more than 2 hours to practice it at a slower pace and several runs to commit to memory.
There a better books out there. I'm not sure how they decided what to use and not use. I listened to the audiobook and I had to play at .6 in order to work on the pronunciation. This is not suited well for those learning the language or a tourist.
