The only positive for me is surprised to see that in addition to USB cable, there is a USB cable / power plug, very convenient for devices that can be recharged by USB without having to put the on the pc. For cons, the USB cable is too long and thick for my taste, and therefore takes tons of space on the desktop. And then the big downside is that my 500gb external hard drives or more (I have not tested with lower capacity) are not recognized ... So I can read my usb key.
