Has anyone tried out the Siig USB 3.0 & 2.0 hub with ethernet port. It seems to fit my needs (adds usb ports & ethernet for rMBP) and can be purchased relatively cheap($50). I plan to use it mostly on my desk and I'll just use the built in ports when the computer is not being used there. The thing that is worrying me is the lack of reviews, I can't seem to find any. Also I am wonder how the ethernet port works I have heard they sometimes have issues connecting after sleep. If anyone has knows of any alternatives with usb 3.0 ports and an ethernet hook up that would be great too.
