If you are constantly plugging in devices I've found that hubs which are at a 90 degree angle are inconvenient. In order to seat the cable you have to hold the hub down otherwise it will move.
A hub that sits at an angle doesn't have this problem. I have both the 7 and 10 port Satechi hubs and they work beautifully. Most link ports deliver less power to the device due to the linking causing my iPads and iPhones to complain that they aren't charging. Actually they are, but it just takes a long time. Even my MacPro USB 3.0 ports have this problem. The Satechi 10 port has 3 ports which are not linked but just charge so these ports don't cause the devices to complain that they aren't charging.
