I listened to it after being recommended by a senior at school. Looking at the curriculum, the sections were organized so well that I could immediately listen to what I wanted. I'm a bit sensitive to sound, so I'm very concerned about voices, but I don't think there was anything that bothered me while listening. It was much better than studying from a textbook because the examples were good and easy to understand. I think it's worth it if you've learned some C#, and it's worth investing in for someone who's learning on their own.
