I haven't owned or tried one. It looks pretty similar to the LSD2 or a Busman mic (can't remember the model name). There are a lot of LSD2 and a few Busman tapes on the archive, so those are a bit more of a known entity. I'd be tempted to go with the known entity rather than venture into the unknown, but that's just my conservative approach.
I liked the way my LSD2 sounded. It's just that I used to get confused on my orientation and accidentally point the damn thing towards the bar rather than towards the stage, usually when I hung it upside down, running mid/side, and was drinking a lot. I think that last item was the real problem, but it was easier to blame the mic.
