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.

I am a returning customer I am a returning customer. I have ordered from Vipera starting with 3 L7s back in the 2021 bullrun and 1 D7. I spoke with James back in the day and felt he was extremely helpful and knowledgeable. Since then I have grown and have come back and ordered from them in 2024. They have very competitive pricing and are a trusted supplier in ASICS.

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!

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.

Good service. Highly recommended I bought an Antminer from Spain and I received very fast and all very good. I had many doubts and questions and the support team always responded quickly and very well. Highly recommended. Compré un Antminer desde España y el envío fue rápido y el producto llegó bien. El servicio de atención atendió muy bien a todas las preguntas y dudas que tuve. Sin problema, muy recomendado.
