Useful and stylish

I used it on: PC (Windows Vista and 8)
My comments are:
1 - Design: 9/10. Modern and sober, the object is elegant. The blue LEDs are not disturbing because they send their light upwards but become shifted in discrete positioning. These LEDs light up only when a device is connected; they remain off if such a device (phone, ...) is single charge.
2 - Practical: 8/10. Catches are inflexible (some must be forced to enter and to remove the USB plugs). But the Plug and Play side is pleasant and safe. As for the practical side of the on / off button, I relativiserai because I prefer the extinction to remove the power supply plug directly (this prevents residual consumption of the transformer and its vulnerability to power-line surges).
3 - Stability: 9/10. The 4 anti-slip pads underneath stabilize the unit on most media.
4 - Speed: 10/10. The effective transmission line with promises, even if simultaneous of use of several devices (test: a Bluetooth Transmitter + 8GB USB key being emptied + Photo 16GB CompactFlash card + WiFi key).
5 - Reliability: (for now) 10/10. I will return change this comment if I have a concern about that.
6 - Suitability for use: 10/10. 7 The definition of outputs / inputs is, in my opinion, suitable. 5 would have been a minimum, 10 is often too.
7 - Various: The fact of plugging in forced for office use. But, in another sense, it relieves lordi of power supply. FYI: if ever (this is not my case) The power supply were to be faulty, the socket is standard and can be found in the current trade.
I am satisfied and recommend it, I use it daily for several weeks.
