This quick-release adapter is a simple design, but a great idea.
I play among others in a cover band where we have to set up all our own gear: instruments and amps, PA and microphones. Having the quick release adapter installed makes for easy and super-fast setup and breakdown time.
Also, having the adapter mounted on top of my K&M-stand and the microphone and mount neatly tucked away together, makes sure there is no damage during transport.
A good, practical idea if you ask me.
