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.
I had ordered another batch of 10 which showed up today but without all the accessories so I was able to put together some power cables and USB cables and get 5 up running tonight. Once i get the cables I ordered ill have them all up and i can add the ones i am getting from this group buy to the extra 10 port hub connected to one of my miners doing GPU Scrypt mining I have both running right now with no issues. Other then a small issue with the first modified CPU miner not disabling the BTC core and drawing way to much power I was able to get them up and mining within 15 min after I had all the right links and software to gether
