I bought the Ibelink X11 that made about $7 a day, and sold it. If I was to buy this I would probably try it with http://www.awesomeminer.com/screenshots.aspx software, that is not a pool, but software that switches the coins you choose based on profitability. I am not affiliated with awesome miner, but this was my plan, and I would be curious to see the results. Please take a look and let me know your thoughts.
