The robustness is only partially satisfactory because the stick does have a brushed aluminum casing, the end pieces are made of simple but each acrylic. For me the stick is pretty claimed and taken anywhere. This is a small piece of one of the plastic parts has already been solved and the USB connector forward now wobbles slightly.
A red LED indicates the read and write operation by flashing. These lights through the acrylic on the side, but is seen in daylight barely. For use on the car radio but again very good, because it is not so bright and not so much distraction.
In total, he made a fairly decent impression and mainly by its relatively fast data throughput much joy. Form Technically you could work on the side panels of plastic something, otherwise there would be full 5 stars from me.
