This is a regular popfilter/popkiller that does what it's supposed to do, meaning reducing/removing popping sound (fast air pressure on the mic created by plosives like "p" ) during recorded speech or singing. That's exactly why I bought it for.
Only the neck is moving, not the popfilter itself. So don't fear to see the screen balancing, it won't. The neck is long enough to place the popfilter from a reasonable distance to the mic or the attach. The neck is easily adjustable but doesn't move when placed. It's sturdy.
I use this popfilter in my non-smoking homestudio, so it never moves outside and only face vocals (and a bit of dust). Got no issue with it so far.
