I have not purchased this shock mount separately, it came with my Blue Kiwi. I simply wanted to state that the Kiwi is AMAZING... this shock mount, not so much. The thumb screw broke upon over tightening, but even at its tightest it was still slipping which caused me to break the thumb screw off while tightening. I went to Lowes, picked up a new screw and a wingnut for $1 and it actually works better than before. So if you are in my situation and your thumb screw breaks DO NOT SPEND $200 ON A NEW MOUNT. Go to Lowes or Menards and buy the parts, easy fix!
