Never Shipped Purchased ASIC
Ordered one ASIC as a test order; Vipera never sent it. They simply took my money and ran, they have not issued a refund as of this writing. Do NOT trust them!

CAUTION!! Added Fees!
I purchased a single Bitmain Antminer S21+ 235T from Viperatech from their USA inventory in April 2025. However, it arrived owing $112 COD for "brokerage fees", having arrived from Hong Kong. I tried calling Viperatec, I tried emailing them, and finally, after threatening to write bad reviews, they responded on Whatsapp. They refused to refund me the brokerage fee, despite me having specifically ordered from their USA stock. Instead, they offered me credit toward future Viperatech purchases, which I wasn't going to do. It was simply bad business. They changed my order without telling me, then increased my expense, and refused to give my money back. I would not order from them again.

Very professional and helpful with technical issues
I never had any issues with ordering asics from Viperatech. Deliveries always on point and not a single issue with any of the asics I bought from them. Customer service is quick to respond to any demand via the live chat on their website. I once asked them about some technical questions regarding a new firmware that just got released for an asic I bought couple years ago and they gladly helped me.

I gave them a 5 star review just to warn all the peoples who only read these 5 star reviews. THIS COMPANY IS 100% SURE SCAM! Read the reviews about this company on other reviewsites. Note that most of the positive reviews are from peoples who never gave a review before in their live and a lot of them are from Bangladesh. Be warned, if you buy from them YOU WILL LOOSE YOUR MONEY!

Excellent Stuff
They recently shipped me a 216T miner. I don't usually take the time to write reviews, but everything about the experience was excellent, from beginning to end. Every email was promptly answered by them. They provided a complimentary two-year extended warranty. Please take attention to my request for a Mastercard split payment link. James helped me choose which pool to utilize and which PDU to use. I'll purchase it again.

I purchased six miners from VIPERA
I purchased six miners from VIPERA. Everything was delivered within the 7-10 days that were promised. They also have excellent customer service; however, because their phones are often busy, use the live chat feature instead. If I have any problems, I can always get in touch with them, and they assist me immediately away via chat.

Credit cards are rarely seen.
I wish more resellers took Vipera's credit cards. The assurance is worth the processing charge.

Deceptive practices. Unprofessional.
Deceptive. Ordered a 4070 super and they sent me a base model 4070. Customer service won't respond to any of my messages.
In addition, take a closer look at the trustpilot reviews. It's all bots.
Honestly compared to other's experiences, I'm surprised I even received a card at all.

I recently purchased 5 units of the L9 from Vipera, and the entire process was seamless. The fact that they accepted credit cards made the transaction stress-free. Highly recommend Vipera for their professionalism and ease of service!
