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.

Ordered miner Ordered miner, told me its in stock and that they can send it as soon as they recieve the payment. They received it and 10 days later still did not sent the miner, say its a delay and offering refund. I need the miner and not a refund, if they were fair they should send a partial refund because of waiting that was not the deal.

The delivery was much faster then anticipated The delivery was very fast. We had our miner in less than two weeks. We had some issues getting it started. We contacted customer service and they responded from overseas in less than 6 hours. Our problem turned out to be AI Protection on our Asus router. After correcting that, we were up and running. Currently planning our next miner purchase. Thanks, Viperatech!!

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.

James and the staff were super… James and the staff were super accommodating. They went above and beyond for a guy in my situation who is just trying to scrape together all the money and credit card limits I could to get a miner. It was an arduous process. They even stuck with me when I thought I might have been getting charged an unfairly high price. So, very good ambassadors of the crypto community for someone new to ASIC mining. It worked out just fantastic in the end. I'm waiting on a refinance to come through and hope I can buy more. If it comes through I will buy the next time with just a few clicks and not take up so much of their time. If I could give any constructive feedback it would be to have an option to split cards more like eBay does it, where the user can select the amount from the one card and process it. Also, the price on the website for the miner was not up to date, so maybe a little disclaimer in red that says something like, 'Item price is the best estimate and subject to supply and demand constraints. Though, Vipera does offer competitive pricing compared to other mining sellers'. But, I know how challenging full stack Web Development is.
