I use this to swap between a Rode NT2A (a fairly heavy LDC) and a Rode NTG-3 Shotgun. It works fantastically for both. Never had a difficulty with either mic. slipping or even rotating because of the quick release. (The boom I put them on is another story.)
Nothing but praise for this product.
Getting another soon.
Wish I could buy just the microphone part because I only use them on one mic stand.
