I use this mic for recording all types faiire, gongs, dulcimer, guitar (made by a voice) has a pretty impressive sensitivity (heartbeat easily visible!), Always pay attention to the Chinese counterfeiting.
Finish money at the time and has tarnished spots appeared (looking solution to clean them ^ ^) but do not affect the sound.

OVERALL OPINION

I use now for over a year and a half
What I like most: the look homemade, with the response curves made by hand (at the time), while the manual in Russian only ^ ^, the sound quality
What I like at all: the appearance of these spots
This is my very first microwave and now I bought a mk319, once fell in we want to try them all!
