I mounted a ZOOM h1n on a microphone stand with a foam windscreen on top, and two fingers away, this pop filter. It stops the air from "f"s, "p"s, "t"s, etc., really well, and the fact that it's double plays an important role. It says "made in Germany" on it, the mounting system is solid and doesn't wobble, and the arm stays in position once placed. You can find positions where the arm doesn't hold, but that's normal, because you can't rely on just a few segments to keep it fixed. Sound Creation's services were very good, as always.
