Didn't want to spend too much on a measurement microphone for my home studio, so this one was perfect for me.
Pleasantly surprised, very flat and neutral frequency response and highly sensitive. Pretty handy to look for standing wave nodes with! Also works well as an instrument or ambience microphone.
The only complaint I have is about the clip. Far too tight and rigid, and scratches the paint job easily with its sharp edges. So save some time and hassle and buy yourself a good clip.
