I think your course is well organised and is great for beginners as well as more advanced. I've only listened to about 30 lessons so far. I like that at any time I can review lessons. It's also great to be listening to native speakers. Unfortunately there is no short cut to learning a new language especially when it comes to tonal Asian languages. Conversation context is great.

Seeing the pinyin makes a big difference. I like to picture it in my head when composing sentences and having the tones works helps a lot. Your product is great! Especially now I can visualise the tones. Your voice is pleasant, calm and relaxed so that it doesn't get annoying if its playing in the background.

Thanks for making this available. You guys are doing a great job. I hardly use my iPod for music anymore :-)
