I bought it mainly for its part "of ISO Mount", but its DUAL mode (boot on an ISO and hard disk usage in parallel is simply fabulous. Any computer technician should have this item with him. Easy to use, in use for several months now, I see no sign of aging of the inclusion of the touch keyboard. By cons, USB3 cable a bit short (and too rigid). Please make sure to unplug "softly" the decision microUSB3
