As a particularly smooth-running I would not call the Dynamo well, but he looks solid processed, runs smoothly and delivers even at low speeds sufficient tension - is a total quite recommended if like me you have come just a replacement for in the years Dynamo investigated. However, one should ("overvoltage protection by adapter") not be fooled by the description of this article lead us astray - there is no adapter, the surge protection is built! And so this article is the same as for example AXA - Dynamo BASTA ~ mounting side left ~ metal design or BASTA Dynamo ~ the mounting side and a few others - a price comparison may be worth doing well! ;-)
