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!

Received 4th machine from Viperatech Have purchased 4 miners at Viperatech in the last year in 4 separate transactions. Always received what I paid for and these 4 machines are running to this day. I am planning on getting a 5th machine and would not go elsewhere.

All Perfect , trusted Seller All went very smooth , trusted seller, follows you till the end. Looking foward to buy more Asic. Thx for everything

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!
