The included USB cable could be a bit longer, but it makes a stable impression. The ports go quite tight, it falls the infected not by itself out.
So far, the hub with all connected devices (memory sticks, card reader, GoPro) works fine, it worked well plugged directly into the Mac.
Very nice, I think that the 4-Port Hub requires no additional power.
A decrease in performance between the hub or directly connected so far I could not identify.
Conclusion:
Highly Recommended for all those not suffice their existing USB ports and want to have a visually attractive hub.
