Pre -> at me the HUB runs flawlessly so far and achieved the typical USB3 speeds on all ports.
The installation was a bit fiddly, was perhaps also to me.
Have the first stroke from the 5 inch panel separately, do not know if that would have been necessary.
Then open the metal casing, cable plugged in (power on Molex), lid back on it and then the "fiddly".
With infected cables and little play the shutter tighten again.
After that, the big test - to> Calculator.
Right away everything worked properly. Only the "Fast change" switch does not open up with. What I've found is, however, that the data lines are switched off seemingly faster load does neither my Nexus5 (it recognizes still a USB connection) nor my Asus TA100 "TabBook".
Finally, I also wanted to get only more easily accessible USB3 ports and I :)
