Personally I believe Butterflylabs.com will deliver its first few rounds of rigs without any issue at all other than the fact that they greatly underestimated the work involved with manufacturing such chips. It is a bit unsettling that they did 100% cost pre-orders without any real promotion other than an earlier shipment than those that waited.

With that said, I still invested $2500 with the company and will not be requesting a refund unless we get well into 2014 without any real developments. As far as I can tell, they have been refunding customers that request it rather effectively.
