Also before you do business with any BTC company you should probably search Google and Pacer for pending lawsuits. BFL has had lawsuits pending against it in state and federal court alleging fraud since at least late Nov. 2013 but no one noticed until yesterday because they named BFL as "BF Labs" which is an uncommon way of referring to them. Some other mining equipment manufactures have federal lawsuits pending against them for fraud as well.
