Switch without Markel

The cable lengths are sufficient for a "normal" desktop. Each breakout cable is likely to have less than 1 meter.

Switching functions via software or the simple principle "who comes first". That is, what device the first current to the USB connector provides is also switched through. Alternatively, you can switch via software installed by double-clicking the mouse wheel (middle button) to.
Switching works then also very quickly and without hesitation.

A deterioration in VGA, or sound I could not really notice.
Use the switch now for over a year without any problems, strong buy recommendation.
