I've used it. It's not so great with Asian languages, like MMM said, especially if you don't have a plug-in mic or headset to use.

They teach you words and everything as if you were growing up, as in conversational. I don't know if that's your goal, but I hated it. In my opinion, taking a formal course is better than not knowing grammar and just spewing out stuff you're supposed to listen and repeat.
