Dishonest and Unethical
Purchased a Bitmain Antminer S19j Pro (100Th), had it for only 16 days when it abruptly stopped working. I send it back to Bitmain for "Repair". Bitmain tried to fleece me by stating that the boards were "mixed" and that the warranty is void and then attempted to charge me for this. That is ridiculous because I purchased it new and in its original state and sent it back for repair in its original state. When the machine was returned to myself, I faced the same issue, it will not power on and all the while it cost me £110.22 to send it to Bitmain to be "repaired" and then an additional £110 to transfer money from my credit card to my current account in order to pay the repair fees which Bitmain charged.
