Nice site..but Unprofessional support. Hello ..I have been order an asic miner and the condition is perfect.. I was going to suggest to my 200K followers on twitter to buy from viperatech As one of the Arab influencers on cryptocurrency ..so ...I tried to make a deal with the site by conversation number to get more Asic’s ..the customer service agent was not respectful to me ..he told me bad word and he mock me .. and he block me on the WhatsApp … I have a screenshots to proof …I don’t know why big and trusted company like viperatech are hiring disrespectful agent ..so I need an apologise by the agent ..to this bad word to me ..thanks …

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!

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.
