I use this pop filter for my voice chat microphone on my work/ gaming setup.
The low form factor makes this a great choice for this application. I did a few test recordings of me talking into it and sure enough, it does what a pop killer is supposed to do. I have also used this to record rap vocals with decent success. Would I use it on a very dynamic singer? Probably not, but it might do the job just fine, I haven't had the opportunity to test it in such an environment.
Overall a decent quality while also low form factor pop filter that does what it needs to.
