USB 3.0 drivers were from 2012, and did not work, but after the upgrade everything was great. So far I could connect up to 2 monitors on my laptop and now with the Icy Box Up to 4 possible (even tested).
Internet connection is not affected and is working properly. The USB ports to go each and every unit it is previously detected (mouse and keyboard from Logitech, USB Receiver for XBOX 360 Controller).
A small weakness I noticed, which was but properly seen. If you want an actual game play (such. Ex. The Crew) the monitor must on which the game will be displayed, be connected directly to the laptop, as if you have connected the monitor to the Icy Box this remains black. That's why the one star less.
From me personally a strong buy recommendation for all who are tired, to connect all the cables to the laptop.
Delivery and packaging as usual Amazon: fast and without problems.
