Bitmain 9.4TH Hello, thank you very much for 9.4TH, it finally arrived. Communication by email and normal telephone was rather difficult, but I experienced very fast and good communication on WhatsApp. We received a tracking number via email, which to this day has the same status as "Shipment information received HONG KONG - HONG KONG SAR, CHINA", but we received the normal one on WhatsApp. For a week and a half, we were afraid that nothing would happen to our package, but then it arrived very quickly. Thanks Viperatech!

Great experience Great experience, it was my first time purchasing from Viperatech. It was a new vendor to me, and I was slightly nervous. I ordered several KS0 units, they arrived earlier than expected and with zero issues or hassles! Highly recommended, they were also fast to respond via the online chat!

Everything went well Everything went well, the only thing I would like to point out is that the order arrived from a sender in Hong Kong and therefore I didn't understand it came from viperatech. I had to trust and pay the customs duties, if I hadn't done so I would have lost the package.

Ordered miner Ordered miner, told me its in stock and that they can send it as soon as they recieve the payment. They received it and 10 days later still did not sent the miner, say its a delay and offering refund. I need the miner and not a refund, if they were fair they should send a partial refund because of waiting that was not the deal.
