Despite being one of cheaper pop filters available - it absolutely doesn't feel like that. Arm is quite heavy and feel firm and sturdy. It doesn't change position even if you accidentally bump it with arm once or twice. Materials are also quite fine.
Bendable, metal arm is attached to clamp using molded thread - it makes arm easily rotate (unscrew) once it's mounted under own weight but only in one direction - in practice it means that you can realistically only mount it with arm bent clockwise (arm on the left, looking straight at mic, not on the right) as otherwise it'll then unscrew itself from base under own weight occasionally and fall. Especially if you bump into stand accidentally. But it has advantage that if mount it to the left, you can kind of easily, temporarily lift pop filter up in order to dismount mic - without actually repositioning arm.
So imho it's actually really nice design once you learn how to use it since i don't need to reposition pop filter every time I put mic on stand, I can just "unscrew" arm a bit and after mic is in place screw it back in easily.
