They have fucked up again and again, resulting in repeated delays and miners regularly going up in flames (both power supplies and hash boards). They disappear for weeks on end (they're in disappear mode right now), then come back with some bullshit about how they're working on a fix. They know all their X3 hash boards are defective, but make you ship the defective boards back to them to get replacements - at your own expense, naturally - apparently even going so far as to insist that you pay the customs fees for doing so.
In short, their communications have been nothing but lies and blaming everyone but themselves (including customers) for their problems. Their ethics are abominable - they've broken every promise they ever made: delivery schedule, refunds, price-matching, etc. Most recently their master customer service representative Alexey A. threatened that they could ship in 4 years and still be within their contractual rights.
They've promised a measly 50% extra hashing power for compensation, but say they can't ship any compensation units until they've completed the initial shipping queue. But both shipping queues are on hold because the current X3 design is defective and they've probably run out of parts for the X1. Instead, they say they're going to upgrade that one to the X1.5, with 150 GH, which will probably involve putting two under-spec chips on a board instead of their single-chip design. This will require reingineering, of course, which they will doubtless fuck up as well.
At this point, the only difference between BFL and BA is that BFL has been shut down. If BA's legal status weren't so obfuscated, I'm sure they would have been as well.
Agreed. I have no idea how dogie feels 5/10 for ethics and 4/10 for communication is reasonable.
BA makes BFL look like an honest company.
