Batch 1 ROId,
Batch 2 ROId for Avalon who mined Batch 2 and then bought more chips to build and ship Batch 2 to the actual paying customers 7 weeks later and yes, then those customers ROIed.
Batch 3 got refunded,  WHAT??   No one has ROIed on batch III yet.
Chips got refunded.

Did anyone got screwed by Avalon? Please tell me, because i stopped following them after batch 2.

Kudos to Avalon. (FY for being unable to find resistors&capacitors in damn China, but at least you didn't screwed everyone as others did).
