Why would you want to find out more? The software sounds very clunky (you have to press a button to update prices, they don't stream) and manualy enter prices. The spreads are awfull (5 points eur/usd when I checked). But until (if ever) they get thousands of clients the liquidity is going to be the scariest problem, in a fast market you might find yourself unable to get out without massive slippage.
