Arrived in 80 days (not around the World...) . Real USB3. Foto 1: Transfer between computer and 2.5 external HDD. Foto 2: transfer between two 2.5 HDD (both in the hub). When the transfer was at 80% I insert the micro USB external power source. The jump in speed is visible. Good. Not as they say, but better than many others. Recommended.
It is very nice
