Chosen for its compactness here's a reminder about product dimensions:
Height closed with screw ball (no screws included): 43cm
Closed without head height (no screws included): 36cm
Unfolded height tripod: 117cm
Height unfolded in "monopod" (feet together position): 125cm
Height of the only ball (no screws included): 7.5cm
Closed Thickness: 8.5cm x 8.5cm (bag size)
Height screw up the top and ball: about 0.4-0.5cm
Height of the screw up and down: 0.3-0.4cm, the ball just happens to screw a half turn, adequate for the weight of my camera. (By pulling it by hand, it does not spell)
