I've just started the first few lessons and I really like the conversational approach to learning and the additional form of testing that follows. Unlike other learning platforms that I've tried that encourage you to speak, Rocket's approach of using voice recognition makes it into a kind of game where you feel that speaking correctly matters. I also love how you can stand in for one of the speakers in a pseudo-realtime conversation. It feels that one step closer to learning with another person. On the negative side, I find the male teacher to be a bit too 'smily', like he is talking to children. This isn't especially off-putting when we get to the actual conversations and explanations but it doesn't really help with learning. I guess they wanted the male and female teachers to have some kind of rapport with the students but it feels forced.
