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!

Fast and reliable Purchase from Ecuador, the miner arrived on time and perfect condition. Recommended. __________________ Compra desde ecuador, el minero llegó a tiempo y en perfecto estado. 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!
