Great mount to use with microphones or in my case LED light. You have three cold shoes for different accessories. Screws onto the bottom of the Smooth 4 and I can even continue to use the tripod using the 1/4 thread at the bottom. I have one of those clamp rings that fit in the gimbal but the LED lamp is in the way of the focus knob, this lever allows it to be positioned easily and the lamp can be pointed in any direction without stopping the movement. suspension function. Recommend.
