I also received 2 units from zoomhash but he did not send the USB cable like he promised in his listing on eBay and the web site.  This may cost him on his feedback as when I messaged him he said it was a mistake and I'd just have to buy them elsewhere.  EDIT:  Zoomhash apologized for the mistake and reimbursed me in BTC for the USB cables.

I have the 2 units up and running and have everything ready for the one I will receive from this group buy (hopefully soon).

The units I have are hashing great.  They are the gold fin ones.
