And that was definitely the right choice.
For video recording, the KK would not suitable, since the ball can indeed been relatively easy and fluent move, but not for video enough.
In all other respects I am of the KK over excited.
I use it with the Manfrotto 055XPROB.
An ingenious combination. Even under full load,
"Canon EOS 450D + Speelite 430EXII + Battery Grip + Cannon 55-250 is" nothing wobbles there.
The KK can also be under this "burden" nor properly in every possible position maneuver and holds bombproof Camera.
Very nice is that you can fine-tune the force with which you can move the ball / needs. This is especially for heavy cameras advantageous because otherwise the whole combination could begin to move with proper momentum when loosening the bracket.
The build quality is also very good. The KK fits comfortably in your hand and gives you the impression that one has something High quality in hand.
The KK is therefore definitely worth a buy recommendation !!!
