Received yesterday and immediately installed I only have praise for this hub for. I had previously used but total satisfaction. This has many advantages, first there is no need for an external power supply to be able to connect smartphone, tablet, external hard drive and memory card reader. Second positive point: it can manage the battery recharge an iPhone which was not the case with the previously used hub. Third interesting point is the correct size and especially the cable is long enough to not be "glued" to the machine and not too long to clutter unnecessarily. Fourth it really is USB 3.0 and therefore the transfer capabilities go with it.
