Unit with small defects

Unfortunately, the problems begin when assembling. Due to the cable lengths an attachment only comes in the front frame section or the vertical handlebar tube in question. Unfortunately, no mounting hardware (such as a suitable clamp and a lug for the Dynamo) are included. I have resorted to cable ties, but had to extend the mounting holes.
Due to the position of the frame I have either the switch in view and the status LED can not see, or vice versa.
As a mini-USB port is mounted, I had an adapter Mini-Micro between plug and stuck my smartphone, which proved to be bulky. I promptly left when descending hang it - the adapter plug was bent and unusable.

The real purpose but the part fulfilled properly. On my test drive over 60km at an average of 15km / h with constantly activated display, navigation app and GPS active state of charge of my Galaxy S II in approximately remained constant. So you can even long trips without having to worry about are when charging the smartphone before.

Update January 2014

Apart from the assembly defects I am to this day very satisfied with the device. 2012 and 2013. I have each made cycling with 1500-1700km with a daily average of 100km. And I've used my Samsung Galaxy SII to navigation and track record. Even with display my smartphone was evening always fully charged, ie the charging current generated enough completely.

Conclusion: price / performance ratio second to none, but I would rather spend a few more euros and it get a device that I take out of the package and can be immediately installed with a stable mount without problems.
