The CS FS-Pro comes beautifully packaged, with English (illustrated instructions). Assembly is not an issue, and thanks to the viiieelen settings the appropriate position should be something for everyone.
I have the belt equally loaded with my maximum weight, ie Canon 60D, Canon Extender 2xII and the 70-200mm f / 2.8! So hang almost 3kg off and you have to have trust, let go of everything :-)! After a long time I can test but say the belt holds !!!!! The opening clips are doubly secured, the metal ball of the plate with circlip bombproof, but rotatable and movable.
Very nice solution: the rapid pull adjustment! The possibility of long / wide lenses to secure the enclosed second loop, or the whole system thereby stabilizing really thoughtful!
The comfort is superb thanks to the wide neoprene surface. I have only made a 1h tour, and not feel the camera. Before, I had to NEN few minutes long neck from Originalgurt :-)!
Conclusion: The price is steep, but comfortable, fast operation, and also the safety of Cam Make ME easily see over it ;-)! I would buy him definitely be back !!!
