Customer service was on point Customer service was on point. When I placed my order I paid for expedited shipping. When my order did not arrive in the time frame I expected I have contacted their customer service. They were able to push it through right away and in addition upgraded me to a higher hashrate miner. Yes shipping still took several weeks but that was outside of Viperatech Control. On their end they have resolved my issue right away and made me feel better about the delay by offering slightly better product. Thank you for positive first time experience with your company. I am always a bit weary purchasing Asics from a new vendor.

Made the process easy and fast This is my first time ordering an asic. I picked this site because it accepted credit cards. I ordered an asic for the November Batch (15-30th) on November 20th, and it was delivered on November 26th. I had many questions as I'm new to mining so the support chat was very helpful and they told me exactly what I needed.

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

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 …

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.
