The first major use today approximately 120km (motorways under construction and roads). The support is "stuck" on my dashboard (on a flat part and not rough that I think it would take on a somewhat rough part, but my dashboard is largely bulging part so the carrier does not adhere not) and once it is blocked (with the suction cup locking mechanism), he must go to make it move ... I tested a very bumpy road (perforated asphalt covering old broken pavers ...), and the media does not move a muscle! Obviously, the GPS / Smartphone tremble a bit but that's normal. The maintenance of the phone is very good, the clamps do not open pdt the road, at the edge of the plastic clips protects the phone from scratches and maintains the potential at the same time (plastic lined to block the phone).
