Suction cup mount for my Tab 10.5 inches

Actually very good idea, you can use if need be as Navi Tab and place clearly visible. Only, here comes the theory and practice, make time there problems here. For me, the holder and thus the tablet wobbles extremely. Then the next problem, my windscreen is slanted, so I always stumble against the windscreen, because unfortunately the distance from the suction cup holder is not adjustable and too short.
It might be appropriate to try the whole time on several vehicles.
