In operation, a blue LED lights up very bright (they've taped with Iso-band) and can quite disturbing.
Half point deduction by.
Another half point I draw from because of the packaging. Normally I always prefer an eyebrow when I read reviews where customers assess the packaging but with this one I got to sweat and can say without exaggerating: Such a bad packaging I've never had!
Funny additional information for people who bought this part for their Raspberry:
-USB 2.0 completely enough not support USB 3 out since the Raspi
-Another Power supply is not needed, the Rasp is connected with a USB cable to the hub and supplied directly via the connection with current, ie the micro USB input from Rasp is not occupied. Sounds weird but is so: D
