Price / performance is almost second to none. For little money you get a good, stabieles and good looking product. Clear recommendation!
The cell phone shell is also very well done. The Galaxy S3 is tight, has to be taken abewr enough to play clean. Important to me, Aich the port for an AUX cable remains free here. The solution with the hinged back support above I find great.
Now the only hacking, the arm. Although this is about different joints moved in any direction, however, rasterized, so you probably will never find the 100% Perfect position. And, as I think a car addict downside is the not far enough leads away the arm of the disc. I drive an Audi A3 when I have charging cable and AUX cable to the unit, it fit very spack between car window and Amatur. If the arm 1-2 cm longer would the problem already from the world. But as I said, that can vary from vehicle to vehicle. The steeper the disc, the smaller this problem.
All in all, strong buy recommendation!
