I have purchased 2 butterfly lab ASICs. I purchased the first one a while ago and the second one more recently (which i feel is more of a mistake now). I still have faith they will deliver their units though as i read they had their ASICs linked to an android tablet mining at a bitcoin conference in the US for everyone to see. They have a few videos on youtube showing their concepts and I hear they have been waiting for their boards to arrive (supposedly).

I'm keeping my faith, although it does seem there are A LOT of speculation they are just running a long term scam. I can understand if they don't want to ship out all their mining rigs at once in fear of watering down the price of btc (and i guess it makes sense they're shipping out the low end 5GH/s models first then moving onto the higher end ones). Incredibly frustrating but patience is a virtue.

Really hope these do come to fruition!
