Brinno ACC1000P Camera Clamp Plus - Large, Industrial, Heavy-Duty Camera Mounting Kit with Magic Arm and Extension Poles - Adjust to Any Surfaces, 360° Rotating Tripod - Universal ¼” Female Thread

This is the best small camera mount system that I have seen. Strong, sturdy allows for size adjustments. This can be used for more than just the Brinno camera. It would fit a GoPro or a small DSLR camera..

I like that you can really torque this clamp down. That part doesnt budge. What i dont like it that for an almost $200 clamp the nuts to tighten the arm that holds the camera or your phone are plastic. It comes with a special wrench to tighten them down but the risk of breaking them while trying to tighten or even loosen then bugs me a bit. I will but some metal lugs to test. Other than that though the clamp isnt going anywhere
