I think that it is a very good USB hub. Duch the 10 ports can be a lot of USB devices anschliessen.Auch something bulky USB devices (smart reader, over broad USB sticks) you can connect almost any problem without which devices get in the way. For this purpose the hub 3 has angled connectors Be moved and another on top of it. I have several hard drives, scanners and connected on without that I had to put the corresponding power supply until now. On the whole very satisfied with the device.
