overpriced miner, and now they are not even hashing to the speed they were telling you... looks like the S3 first batch. It suck that those company are probably hashing with your machine and give them to you once they have been paid off... you can see the network hashrate dropping alot when those are shipping.
yup during shipping hashrate was like 30-40 ph/s lower 240-244 now 272 
and diff gonna jump now was looking good for a negative until last 2 days
