So far, my third bracket and by far the worst. Had been each O2 XDA mini and a one for my Motorola Milestone 2. These were precisely, all the buttons, functions etc could be used. With this, everything is different. The Xperia S does not fit purely tidy, there are gaps at the sides which is why the phone wobbles, the part with the holder vibrates while driving and the volume keys can no longer be operated. The only thing that is good funktiert the suction cup that holds really bombproof. There would, however, also done something less. Compared to my other supports you need to leverage an extreme effort, something would have been less. The two pivots are of the operation also produces annoying. Will keep the product for lack of alternatives, but the suction cup had now replaced by my old Motorola bracket.
The anti-slip mat is super incidentally, as a free gift but was not the flows included in the evaluation.
