In my home recording studio I probably have half a dozen of pop filters, and I can't even remember why I bought this one - maybe I needed a spare for some important session. This is inexpensive, but even my golden-eared friend, a well known recording engineer who sometimes records drums in my studio, couldn't tell the difference between this and a much more expensive, brand name filter in front of my trusty Neumann TLM 193.
PROS: price, it works just as well as more expensive pop filters
CONS: the flexible arm could be a bit more flexible, but it's OK and the mic stand clamp is quite reliable.
