bought this for a used Blue baby bottle mic i purchased. Needed an all purpose shock mount. Have been looking at other options for my other mics, but this worked great. If you have mic's of different sizes, this will do the tric. due to the screw in place, you can use it with pretty much anything. even SDC if placement is not an issue. I will deffentliy buy these in stead of the metal shock mounts thats costs twice as much.
