Compact Microphone Recommendations for the BMPCC.

Having read through this thread and others relating to internal audio, I was wondering what other on-camera options people have tried on the BMPCC?

I'm hoping for something compact that will do for shooting B-Roll. It only needs to be good enough for atmos and not featured sound. Any thoughts?

Hi, i'm trying out this thing: "Gembird MIC-222"
search for that on amazon
its ridiucously cheap but the youtube demos of it sound surprisingly acceptable.
