It has been criticized in some reviews that the Dock (standby) has no way to charge an iPhone or another phone such as "that's true, but does not bother me.
Also two Thunderbolt ports are available, as it says in the description, of course, it would have been smart Belkin to describe that one is used to connect to the Macbook. I myself have the other port still free, because my display is connected via HDMI.
More genutze hardware is from the dock of the Ethernet port, audio output, USB port for printer and as a power supply for my little boxes. As a keyboard I use Bluetooth keyboard and Magic Mouse from Apple, both in harmony with the super dock.
I have not encountered any problems when working with the dock, it does what it should.
So to me, there is a strong buy recommendation!
