In the version supplied me nothing unusual smell neither Schadfstoffen, even after softening. I have attached the wall holder with a small metal hollow wall anchors to the wall. , Attracted 10 hole in the drywall, dowel purely with matching assembly tool and then use the screw admission to the wall. Keeps bombproof and twists a millimeter.
The universal holder fits perfectly for the 10 "tab, for me it is clamped in landscape mode, the strong tension holds the device firmly enough to prevent falling out safely. They too are" claws "of the recording slightly rubberized, so I without concerns would rotate the clamped device. With the best will, I can not imagine that here could fall out something.

Overall, I think this attachment system perfectly adequate and flexible and would buy it again at any time.
