Sounds and looks great! I like the size of mic. Ideally to put in the
pocket :)
You wrote that mic is not sensitive to wind (the recording is the best
proof!) but of course it's better to use some fur? Do You plan to add any
to the mic kit?
Great that it don't needs additional powering. I don't like carry battery
boxes. ;)
And the most important question. When will we know the price? At the end of
April? It so much time!
All the best!
