It has all the right content, but in all the wrong order. After struggling with the early lessons I realized I had to start each lesson at the bottom, learn the simple words and phrases and then make my way up to the longer stuff at the top/beginning.

Then after struggling with 5 lessons of long, complex multisyllabic structures, they finally introduce you to the endings and tone pronunciations. This means that the lesson structure is in the wrong order too.

Technology seems great, lesson ordering and general approach seems to need a lot of work.

Finally, this is likely a personal choice: but when I'm trying to learn Chinese I really don't want to have an exuberant english guy shouting at me about how excited he is. As I realize some may like this, I'd like an option to filter out Dave and just learn from the native speaker.
