Significantly cheaper than the original part. Unfortunately it takes a fraction of a millimeter to the locking is done correctly on the ball of my 234RC monopod (the small brass safety pin does not engage).

The quality of machining of the piece must be random because I see that, moreover, another surfer is satisfied.
