BFL is real. I live about 20 mins away fromm their lab. Ive been there and saw all the different systems they are selling. Yes they did have a few of each up and hashing, not at full power because owner said the were still working on heat issues and software stabilizing. but all in all I believe them because I saw them with my own eyes, they gave me and my buddy a tour of the entire place. Its legit, slow, but legit.
