The external USB hub by Delock is a good choice if you want a space-saving way more USB ports required. Designed to connect 4 USB devices, the device itself has a power supply, so that external hard drives, burners, etc. have no problems. Only annoying is the permanent and very bright LED. Here, the manufacturer would have to either omit or selbige only with active use of hubs shine. The latter is only my personal opinion and only a tiny fly in the ointment, because you get a very solid processed, reliable stroke at this price.
