Bitmain 9.4TH Hello, thank you very much for 9.4TH, it finally arrived. Communication by email and normal telephone was rather difficult, but I experienced very fast and good communication on WhatsApp. We received a tracking number via email, which to this day has the same status as "Shipment information received HONG KONG - HONG KONG SAR, CHINA", but we received the normal one on WhatsApp. For a week and a half, we were afraid that nothing would happen to our package, but then it arrived very quickly. Thanks Viperatech!

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

ASIC miner review. One of the only miner distributor accepting Credit Cards. Fast, smooth and easy purchasing process. Good customer support. The status of the order can improve, as it showed "still in process" when it was already long shipped.

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.

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!!
