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.

Viperatech is legit but takes patience. US company location. Can pay with cryptocurrency. Like all ASICs you generally have to prepay for a nonexistent product that doesn’t get drop-shipped from China for 2 to 3 months which does suck. That being said Viperatech is trustworthy and so is Jasminer which is a huge plus!

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!

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!
