Yes but to be fair Bitmain is standing behind the problems, and is taking ALL of the loss (including paying for return shipping).  They are the only company reliably shipping 1 Th/s miners and they did it without pre-orders.  They already have a fix for Batch 2.  They are responding to my emails within hours (or minutes) and have been very apologetic.  I cannot think of another company that has been so reliable and easy to deal with so my loyalty is still with Bitmain despite my disappointment at the S2's condition.

The S1's are like Sherman tanks - indestructible, well engineered, cheap, efficient and powerful.  I **wish** the S2 had all of the same characteristics, but still the S2 is the best in the 1 Th/s class of miners - so far.  And when bitmain introduces a more efficient S3? (yeah, hopefully 5 Th/s for 6 BTC lol) I will be there to order as many as I can get.
