By connecting the vessels and only the HUB's connecting to the electricity grid and boots up his computer is ok. But woe to you want to connect another device or disconnect a device from the hub. I have extreme in both HUB's loose contacts. The connected devices are temporarily disconnected and then operate only at USB 1.0. Only a restart can fix this. This can be extremely annoying when you just operates a hard drive ...
Furthermore, the processing is borderline. Connection of the extension cable from the computer is located now a little loose in the hub ...
In summary:
+ Good function if you do not touch the HUB in operation and can turn its power strip according to the work
-Wackelkontakt With serious consequences
-Something Cheap processing
-When Using with power supply units are switched permanently, even if the computer is shut down.
