Good service. Highly recommended I bought an Antminer from Spain and I received very fast and all very good. I had many doubts and questions and the support team always responded quickly and very well. Highly recommended. Compré un Antminer desde España y el envío fue rápido y el producto llegó bien. El servicio de atención atendió muy bien a todas las preguntas y dudas que tuve. Sin problema, muy 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.

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.

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

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!
