First impression: Not reversible, be careful not to force if you plug in a device cable in the wrong way. When starting the PC, if the hub is on, my keyboard is not detected before arriving at logon, so can not access the bios. Result; if I want to go into my BIOS to power up (before you log on to Windows), I have to turn on the hub only after login. My headset SR 7.1 when connected via USB hub that does not. Fortunately, this hub has a switch that allows me to start my flying G27 after the opening session, thus avoiding the dual shabby calibration G27 (bios and session), connoisseurs understand me. For the rest, it seems okay, although I would have appreciated all the cables from the same side (including food), to avoid this effect "hedgehog" that we see too often for my taste. To believe that the designers never use what they conceive.
