Device relatively easy to install. Unclear why unasked a dynamo comes along (old side runners, the will have no longer a man today). Electrical I do not really need. Function as described, however, already shaky the first rain of the display LEDs. Problem: Because after the installation is running the lights on the device, you can take it off when it rains also not easy. After two weeks (in beautiful weather), the device presented then the loading operation. Overall, there is no robust. Have today returned to the dealer, hope returns the money.
