Update: The company is now refusing to refund me the difference until I delete this review. Copy/Paste from email: We aren’t sending you a damn thing until you remove that review. I am now told my extended warranty for my previous purchases are now only 1 year instead of 2 because of this review and to contact bitmain directly for any problems since they won't honor their warranty anymore. Terrible experience with my last purchase. Ordered a E9 Pro 3780MH on October 28. Waited 2 weeks for them to send me a tracking number. Finally received a tracking number after having to ask for it. Tracking number never moved/updated (pretty sure it wasn't valid). Another 2 weeks later I still have to message them to be told oh they lost the package in transit (total bs). Another 3 weeks later I received the wrong E9 pro... They sent the E9 3680MH which again I have to email them about. They first ignored my messages and after 1 week and a half of sending messages, I finally get an answer. The answer was: Oh we we're out of 3780MH. I then messaged again waiting for a reply to get refunded the difference in prices of both miners just to be ignored again. I'm tired of having to be the one to messaging them 3 times in a row just to get an answer.

I recently purchased the IceRiver KS0 Pro from Viperatech, and my experience has been nothing short of fantastic. The product was delivered exactly as promised, meeting all my expectations and more. What really stood out for me, however, was the exceptional support.

Great overall experience

Myself and friends have used Vipera Tech several times for purchasing mining equipment. They are the best in the business. Highly Recommended!

The process was seamless. This was my first time buying a miner and I was super nervous with spending this type of money and waiting on it. They answered all my questions and my package arrived with no problem!!!

Communication in making my purchase prompt and efficient. All info provided exceeded my expectations and I look forward to doing future business with them.

Miners were perfect. All works. They are super careful to get your order right. Shipping was fast and perfect. Good people to work with!!!

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.
