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 Matt Crawford

This very close ( if not exactly the same as ) to Neewer Professional Heavy Duty Carbon Fiber 360 Degree Panoramic Gimbal Tripod Head and definitely has the same problems ( see 3 and 2 star reviews for that one). The design is also very similar to Neewer Professional Heavy Duty Metal 360 Degree Panoramic Gimbal Tripod Head. The later head was around for a while and there are YouTube videos describing issues with it and DIY fixes for some of those issues. Search for "Neewer Gimbal Review" on YouTube for details.When rotating in horizontal plane clock-wise the bottom screw starts to tighten, which makes horisontal tracking of subjects hard.Basically you get the same poor design as the aluminum version that costs around 90$, but pay extra 55$ for carbon fiber part.
