1. The hub now has a non-slip surface that prevents slipping on smooth surfaces of the hubs.
2. In order to operate and hard drives, lacked a 5V USB port. This is now available on the back. A power supply is not necessary for the operation and is not included, but can also be connected if required.
With supplied a 60 cm long USB 3.0 connection cable belongs. Processing I like and the connections are also pretty far apart, so that even thick plugs fit side by side.
In this improved version, I like it even better and I would recommend it.
