Another note regarding the length. I'm not an IT-crack and do not know what you want "13,34cm (5.25") "mean in the name Anyway, it is not the cable length that is (. as mentioned also in the title) exactly 30cm, measured only the exposed cable. Otherwise, at the Ding nix 13,34cm long / wide / high ... Maybe someone can indeed give a hint of what will tell me this value :-)
But: strong buy recommendation!
