I bought the case, because I have already several Sharkoon Rapid Case in operation and I was invariably satisfied so far. From his previous USB2 brothers this case differs only by a little too long time until the panel off after detach. While the proven USB2 brothers immediately go into the power-saving standby mode, the USB3 version begrudge a few minutes. Still 5 stars, because it is basically irrelevant. Top condition / Quality. A cable "USB3 -> USB2" is.
