Nady MPF-6 Nady 6 Inch Clmap On

 It works.
It works fine. Comparing my vocal recordings before and after, you can tell the difference with the absence of those annoying vocal pops. It clamps onto any mic stand and you can contort it the way you want.

 Solid pop filter, strong enough gooseneck
This is a solid pop filter, especially for the price. I bought it to use for my StevePavlina.com podcasts. My first couple podcasts were done without a pop filter, and I noticed some popped p's. With the pop filter the pops were greatly diminished. The gooseneck seems to be strong enough to hold its position, although it's probably easiest to simply adjust the height via the clip.
