Mic is in great condition - see pics

The build quality of the microphone is nice for about 90%. The remaining 10% feels like cheap plastic. The microphone stand is cheap and does not feel sturdy enough to hold the microphone stand, and the microphone mount provide no shock absorption.

The specs sheet says that this microphone provides 30Hz - 15kHz, which does not look like the best, but when listening to the microphone, I think it sounds perfectly fine. It seems like they made up for the lack of high frequencies through clever EQ of the microphone.

The microphone has a cardioid polar pattern, which is fairly directional. When testing it out, it seems like the pick up pattern is about 180-degrees. So anything in front of the mic it will pick up, and anything behind it, it will only pick up low frequencies of. When testing this out on the keyboard test, we heard a LOT more of my voice versus the keyboard, but you could still hear a bit of clicking in the background. During the distance test, we heard a bit of a drop off in volume as the distance increased, but it was not as drastic as a dynamic microphone.
