I just got my 4k+ and it looks really great! The only thing that bothers me is the microphone adapter. It does not allow you to charge and use the external microphone at the same time. There is an adapter for the GoPro that does the trick, but I don't think it's working with our Yi 4k+. Did anyone try that or know another third-party adapter that is actually working? Maybe there will be one in a few months...
