This Hub is (almost) identical as 4-USB port version. Instead of the 4 USB ports you have 3 ports and 1 Ethernet output on this model. On the one hand there are more and more WLANs on the other side have some laptops as a result no longer Ethernet port. Should an Ethernet connection be instructed (Comes in several conference rooms and hotels ever before!) You can make do with this adapter. The function is fine with me.
The cable is in the beginning a bit stiff, but it lies down with time. Through USB 3.0 you have the fastest possible connection, but can also connect USB 2.0 / 1.1 if necessary. The distances are selected such that multiple sticks or plugs easily fit next to each other.
Fits in perfectly well with silver Macs makes even among other laptops a good figure. Am fully satisfied.
