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.

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.

The company delivered as promised! I put in my purchase of the miner oct 29, 2023. The item was delivered nov 28th, 2023 as promised. I will definitely will continue my purchase’s through this company. Thank for your service and prompt response! Great experience! Respectfully, James Nardi

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.

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.
