I bought this together with the dbx DriveRack PA2 to use the AutoEQ function and the built-in RTA of the PA2. I haven't used the microhpone in any other applications but for use with the PA2 it's exactly what I expect. The PA2 also has a separate setting for this particular microphone to flatten the measurement response even further, so it was the natural choice for best performance in the application used.
The included case feels cheap and is made of plastic but it has so much foam in it to protect the microphone that breaking the mic inside its case by normal gig handling will be very hard.
