Is that Victor Lustig?
BFL = lying scumbags, they flatly refused to refund my money and were nearly 1 year late with the shit they shipped in the end.
They were basically selling a money machine - put in a 10 and get back two 20s. It's been done plenty of times in the past for great profit, though not by the marks, so it's a good model for con artists to follow. I am sorry you were had, though.
