As far as the course goes, I started with number one just for context and I am now on lesson 57. I am not sure what level my Chinese actually is, but I have known most everything on the lessons I have finished so far. Although, it has been a great review for me on grammar, vocabulary and tones.

I have enjoyed listening to you and Kirin a lot. I think it was a great idea to have listeners from many different places, but overall, I would agree that I prefer to listen to Kirin's Taiwanese accent. Also, I just finished the level 1 review (lessons 58, 59 and 60).

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.
