It appears to be well made, although I bought a pair and there are some slight differences in the machining of the body that I don't think affects the tonality of the mic. I have so far only used them on one show, but I expect to be grabbing for these mics over and over again.
The frequency response is razor flat, and the mic sounds exactly like the source.
Very tight polar pattern, so position is really key, but essentially point it at the source and move on to the next channel.
This mic sounds amazing! I'm using it on woodwinds in a musical right now and it picks up the flute and double reeds perfectly with minimal leakage of the drums and guitar. I have a HPF on it and no other EQ was necessary. It is the most "musical" shotgun I have used.
