I've been pursuing voiceover for three years. I've been using this filter for the last couple and have had mixed success using it with two different mics (A Samson C01U and a Studio Projects C-1). Unfortunately, errant pops sneak into my recordings fairly often. I will grant that they're quiet pops, only loud enough to be heard with studio headphones. But still, a quiet pop is just enough to ruin the recording if you strive for professional quality. If you're a hobbyist looking for a cheap filter that'll work okay, go ahead and grab it; just be aware that some pops will show up in your recordings. If you're looking for something that will completely eliminate all plosives, I'd recommend paying a little extra money for something better.
