Rausgesucht, ordered and waited for the delivery (habs then let give finally to Christmas). So unpacked after Christmas. The docking station feels quite valuable and well finished to. In the price range of course does not sit all bombs firmly. Ports like USB & electricity are easy to stretch backwards, but is under.
All wired, connected and switched on USB3 port of the computer. Win 8.1 immediately recognized the thing and installed shortly a driver! Thereafter, a 500 Samsung HD502HJ plugged -> immediately popped the Explorer. Power-saving features are also supported by Windows. As it now looks with other operating systems, I can not just try, as not at hand.
So far, a good choice.
