Hello FHeizer,
Many of us are concerned about the legitimacy of the company that made your miner.  Would you be so kind as to answer the following?

1) What address was the miner sent from?
2) Could you post pictures of any paper and shipping documents that were included in the shipment?
3) Have you been able to verify that you are getting the 600 GH/s?
4) Could you give us any other details that you think could prove to us that this company is legitimate?

Thanks for your time.
