The Hub comes with a power adapter, which is almost 3/4 the size of the stroke itself. Because it also sometimes whimpers, I subtract a star. It takes the power supply but only if you have connected particularly electricity-intensive consumers (eg multiple hard disks), otherwise you can also connect without power supply.
I have the Hub on USB 3.0 connected and the transfer rates are impeccable. The USB 3.0 cable to connect included. Who does not have USB 3.0, the hub can operate via USB 2.0 or 1.1.
The 7 ports are well distributed: 2 pieces are on the device (Ideal for USB transmitter), 3 on the rear side and 2 front ports.
A small blue discreet signal LED indicates the operational readiness. What I like in this hub, the intervals. Even thick and chunky plugs fit easily side by side.
Conclusion: The Hub itself looks good and works great. Not so good to me relatively large power supply has fallen, which sometimes whimpers.
Note:
This hub I have received with a request for review by the manufacturer. It was taken in any way affect or content rating.
