For the rest, all is well, tested this mini hub on multiple desktop PC and a notebook PC (no Mac at home, sorry), taken on true USB 3.0, mainly with portable hard drives USB 3.0 and 2.0.
This hub does the job well, it is USB 3.0 on each connector, the transfer rates to / from USB 3.0 hard drives are excellent.
The cable to connect the hub to your PC / Mac may seem short and it is, but I find it actually very practical, personally. Matter of taste, but it is easily cluttered with too long cables.
Finally, practical, efficient, perhaps a little pricey, it seems, but I do not see how such a tool can fail, and the USB 3.0 still has a bright future ahead of him I think .. .
