Already have 2-port sharing Konig hub which works well. This 4-port version is well made and, contrary to earlier reviews, the front A/B/C/D press buttons correspond to the same ports immediately behind - no need to mentally reverse things. Works in conjuction with the Orico 10 port USB 3.0 hub, which is well made and performs perfectly between latest and old PCs with both USB 2 and USB 3 ports. Using XP Pro, I've 3 printers, a Logitech C920 Webcam, Vodafone, Skype, Sharkoon Dock attached to hub which is shared without problems via the Konig hub. Would have liked ability to screw the hub to a vertical or flat surface; as it is, have used velcro strips.
