Unfortunately, it is this central column no Around 90 degrees, this is currently apparently only with the supplied column. The knob at the bottom does not fit through the hole on the hinge. In addition, this column is much more difficult. I will probably mount a leveler on the original column.
For tripods with no 90 ° -Umlegefunktion the product is certainly a great alternative that does not increase the number of accessories (tripod + head instead tripod + leveler + head), therefore three points.
