Some pros: The thing is simple and unpretentious. It does not unwind and does not fall off even with strong vibrations and wind loads. It is used for shooting with a compact camera and fully justifies its purpose and functionality. Cons: The screw securing the swivel joint to the metal part must be immediately tightened and, apparently, fixed with a threaded lock. Without this, the hinge spring is weakened, and the camera begins to dangle.
