Surprisingly scammer, fraud business style Viperatech scammed me, beware! Dont get delusional by their gimmick marketing using CNN interview video they put in their website/IG. Read the 1 star review in trustpilot and you ll know the real issue with Vipera. My experience I bought GPU Nvidia RTX 6000 Ada and I paid full amount for over $8000 in January 2024 (SI-1269) but what I received was RTX A6000 which is the older version, lower spec and cheaper by over $3000!. The product they sent me is totally different from what is shown in my invoice , what being shown in the website and and it seems they ignoring my case. So they are stealing my money by doing this wrongful, fraud business style. Vipera also sent the GPU just wrapped in bubble wrap, without the original box given , no warrant card, no manual ec. It is just a-single GPU in a bubble wrap. and what surprise me more is they sent using a used biscuit box. I still cant believe myself when I received a package in that condition. Dont they have QC/QA? Further to that, prior to my order in January 2024, I chat with them to confirm delivery time which they said lead time is just for few days and in the invoice it stated delivery will be February 2024. The delivery didnt happen until April 2024. After such a long wait, I am really dissapointed when they sent me the wrong product and they totally ignoring me now. I sent multiple email, tickets, call them and use chat function to get their assistance to assist with returning the wrong product to them but they never answered my chat/call/email/ticket and it is almost 2weeks now since I received the wrong product and 3months since I paid the full amount. I still remember how responsive they were before I made the order, and now they totally silent after receiving my money. In summary 1. I received wrong GPU product from Viperatech. Product I received is $3000 cheaper than what I supposed to receive 2 . The wrong product receive comes without any original Nvidia box, no warranty card, no manual given. It is just GPU and bubble wrap. 3. Vipers send the GPU using a biscuit box only. What kind of quality control is this. 4.. I want to return the wrong product but they never answer my email/chat/call etc. It has been almost 2 weeks since I received the wrong product and they still dont want to answer me. I will amend this review if they will guide me how to return the wrong product and to send me the actual product I ordered. stop stealing Vipera!

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

I am a returning customer I am a returning customer. I have ordered from Vipera starting with 3 L7s back in the 2021 bullrun and 1 D7. I spoke with James back in the day and felt he was extremely helpful and knowledgeable. Since then I have grown and have come back and ordered from them in 2024. They have very competitive pricing and are a trusted supplier in ASICS.

I started off looking for trustworthy… I started off looking for trustworthy places to buy asics that has a location in Canada. Now this is the main place I go to buy my miners. Even the preorders went really smoothly. The whatsapp customer service feature is super convenient as well. Highly recommended

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.
