Just a little flat on the fastening system. If you follow what is stated in the instructions, remove the tripod mounting screw by releasing the fastening system via a ring, tighten the lock your device by tightening with a coin currency for example, and insert the fixing screws into the tripod and lock the system with the ring. A little sports like handling. But no handicapping!
In summary, a very practical item for anyone looking to take pictures in conditions outsized!
