Pleasantly surprised by this case. The box works very well in USB in my case. Simple installation. Plug and hot-unplug drive smoothly. No temperature problem, the automatic management of FAN is smart. The only downside as we say certain is the button "sync": Must be pressed for 5 seconds to change the power synchronization mode with the PC. A priori, blue light: the case completely extinguished with the PC (manual ignition against), or even randomly in my case, probably when the USB controller is put into standby mode by Windows ... m **** .. . :) Orange light: the box switches to standby when Windows goes out and back on when Windows starts is (the best method in my opinion). The only problem of this mode: it starts only when Windows starts, so the discs will not be present when loading the BIOS. Not really a problem unless the boot disk is in the housing, which is strongly discouraged. No light: stays on all the time.
