Review on Heavy Duty Carbon Fiber Panoramic Gimbal Tripod Head For DSLR SLR Cameras, Camcorders With Telephoto Lenses - 360 Degree Movable, Arca-Swiss STD 1/4” Quick Release Plate & Level Vial By Annsm by David Carmody

This has the potential to be a great purchase if only the quality control was better. Everything was well designed and machined. The issue I have with mine is the graduated arm is not screwed tightly to the pivot point and moves slightly. I would tighten it but it has a metal plate covering the screws. There appear to be two of them as they can be seen in the small gap between the two pieces. I would send it back for a better one but am headed out and need it this weekend. Time for a bit of JB Weld.
