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.

Ka3 purchase

Bought a ka3 on 12/11 got it sent to my doorstep by 12/22. About two weeks sooner than I expected! (7 day handling time and 14 day free shipping). I am super happy with viperatech. I will be purchasing from them again very soon.

Simply fantastic

Simply fantastic, I had some doubts that it was scam, but it turned out to be an excellent company, in just two days the miner arrived from Hong Kong in Italy I will definitely buy back from them

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.

Received product good company

I ordered a S19J Pro+ on December 13th because the website said they had a bunch in stock. I made this review because I have yet to receive any updates on my order and have read through some reviews saying they have not received their order, so i am a little concerned. I sent an email to them asking for an update December 15th and received a quick response saying it would take a 2 business day delay from when you place the order until you receive tracking, and then it is scanned shortly afterwards by DHL. Also noted that they are shipping from Hong Kong, which I can understand since thats probably where they are made. As of Dec 18th I have not received a tracking ID or any updates. I will give them the benefit of the doubt that they are busy because of the holidays but I am still expecting a shipping label to be given to me for tracking today or tomorrow, or I will begin to be worried. I will update my review once I receive a tracking ID on my order, and will update once again if/once I have received my package.

Edit 1.) Dec 19th still no update, shipping label or tracking id provided.
Edit 2.) Dec 20th Got an email that tracking label will be scanned shortly and got the tracking label itself.
Edit 3.) Dec 21st label is scanned and estimated arrival time is Dec 27th.
Edit 4.) Picked up package from DHL Dec 28th machine is working fine and looks brand new.

Final conclusion, reputable company. Shipping could’ve been quicker but I ordered around the holiday rush so I can understand. Will probably buy from them again.

If I could give zero stars I would

If I could give zero stars I would. We ordered a miner from this company and the manufacture was delayed - completely understand that is outside of their control. However, the way they handled that delay is unreal to me. I spent hours trying to get ahold of someone for updates across multiple days. When I would get updates it would be to tell me to be patient and that they couldn't give me a refund even though the item was delayed by almost a year. Finally, I found out they had the item, but hadn't bothered to ship it. Then arranging shipping took another 2 weeks of me calling. Their employees are rude and unhelpful and there is zero accountability if something goes wrong. Buy from a more reputable dealer. I also noticed that they like to claim bad reviews were paid for by a competitor or not actual customers. That's a cute trick.

You preordered an Item that was not even produced yet, only announced. From then on, the release date kept getting pushed forward which is out of our control. We offered to swap for another in stock model a couple of occasions (as the manufacturer does not refund us), yet you refused. We invited you to try and source the item with another vendor, but you did not because it was obviously not available.

When the manufacturer finally released them, we were not informed that your unit was ready. Once you followed up with us, we contacted them and shipment was arranged. In the end you received the goods-- and you are coming here months later leaving us a 1-star review? Interesting.

Bad 1-unit customer who was offered options during the process to make it right. Go buy elsewhere.

I checked on the status of my order. I got my update quickly. If something bad happens from here, I'll update my rating accordingly. Once I receive my order, I will update this rating to 5 stars.

UPDATE:
Got my miner faster than expected. Very happy!

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!

Arrogant seller - Don’t take time to understand the client needs. Always have a story that doesn’t concern my questions. Very bad seller .

Clown non-buyer.

Perpetual time waster. Inundates our sales staff with a thousand questions about our legitimacy and confronts us about fake negative reviews on a site that isn't even Trustpilot. Doesn't buy anything in the end, then proceeds to leave a 1 star review. Constantly was asking questions about a 9.4T that everyone wants with prices increasing daily, and requesting he pay for it on delivery at our Canada sales office.

Non-genuine experience.
