It comes with the bracket incl. Sucker, a round plate for attaching the car to turn, to attach the suction cup on a flat surface and a warranty booklet (Chen).
The holder is mounted within seconds and ready for use. The suction cup is sitting after installation "bomb-proof" and does not fall down surely. I tested both a disc and a slightly structured table. The surface does not have to be like other cheaper holders, absolutely smooth and even.
The Grade 3 can be positioned easily and secure on the "baking" the left and right with a slight pressure, including Case. The phablet sits so well in the holder so that you can keep it even overhead without "losing" the precious hardware. About a button on the back of the car mount one gives his device again free and can be found there.
A successful product in top quality as I expect it from a manufacturer like Samsung.
