Feedback & precautions

The two flaws I nevertheless noted:

=> 1st fault: tightening the ball is not entirely reassuring if one puts a certain weight accessories.

=> 2 default rubbers of the gripper jaws are not interdependent and can slip during use with a certain load (eg a flash + shutter). It will think about doing it join (glue or adhesive). During a photo shoot, a jaw eventually remove their shoes and clamp down obviously with the flash that sat there.
