I picked up the Swedish modules (1-30) and I'm still working my way through them. If you're an audio-based learner, it's a really good way to learn pronunciation. For me, the lack of visual reference (no companion text until module 11) is really troublesome, I prefer to read what I'm saying, at least in the beginning, just so I have an idea how they correspond. I'm not sure if all the languages use the same scenarios, but one thing that really annoys me is the "now you change your mind" conversational prompts. The course says things like "Say, you'd like a cup of coffee", then "But you change your mind, so now you want a glass of beer", then "he says he doesn't understand", then "tell him you want a cup of coffee." These types of "reconstructing sentences" may be useful for spaced repetition, but makes for truly exasperating conversation.
