Appearance and robustness
Nice overall appearance, with a blue LED on the bottom. The plugs look strong enough to handle a lot of USB drives.
An interesting point: its dual power supply which allows the use of USB media requiring a large power supply.
Negative point for those who are sensitive to power consumption: the LED is always on, whether the PC is on or not, and there is no way to remove it except by turning off the PC power supply.
