The only way to break even from this disaster is if they shipped you a second SP30 along with
the one you paid $4500 for for free at the same time.  Then you would still be pushing it giving
your hosting or power bill just went to double.

The group buy price which clearly advertised   -   SP30 pre-order - Specs: 0.69$/GH + 0.46W/GH
Is what was advertised and promised over and over.  Now they want to back tread to oh well it was
really only maybe possibly probably MIGHT be 5.4TH/s after promising 6.5TH/s ?  Plus a utter failure
on power usage too.
But still dont want to compensate for that.  Oh just give them a coupon for more stuff in October,
Oh yah it will ship again the last day of October, and its all good right.  Please.  
Send a message, everyone who was in the group buy ask for a refund, lets see what happens and if
they honor that.
These bullshit preorder ripoffs, make more money for the manufacture schemes need to end.
