Recommended bracket, tedious assembly

Now have tested about 300 km long, the holder.
But first from the front:
The assembly was a bit cumbersome because despite various adapters the screws only slightly may be purely screwed for fixing the handlebars on both sides, otherwise the screw is on the other side do not hold.
The holder fits perfectly for the SGS2. The rubber bands are not really necessary, but reassuring.
A touch screen operation with hooked elastic band is difficult!
Once assembled it holds bombproof, also various distances over cobbled and jumps curbs have provided no reason for complaint. I could not detect any movement of the plate in both cases.

It is possible that by the continuous stress the hard plastic once brittle and breaks. Then one can only hope that the expensive mobile phone is not affected. An endurance test is the show. I drive about 7000-10000 km / year and will report back after some time again.

For my various phones I have experience with some holders.
This is so far the best support!
