Very stylish and high-performance hub for the Mac environment

The hub looks very good and fits with its aluminum case perfectly to the current iMac 27 ".
I run usually lasting 5 of 7 ports. Although including two external 2.5-inch hard drives (only one USB 3.0 cable), the performance is sufficient without any problems. In my current version of an external power supply with 12V and 5A (as printed) is used. The Hub is at the top of my desk, so that much of the cable falls behind the desk and is so hard to see.
Is a bit unfortunate for me that the stroke off via a button on and off. Since my entire computer peripheral is switched on via a master / slave Steckosenleiste on the Mac with, I must also press the button after each restart. The last switching status is not stored. Here a toggle switch would be better for my purposes. However, the button may also be useful when thinking about this stroke only temporarily used devices to the iMac combines, therefore no penalty. In my view, a very good product at a reasonable price.
