I’m changing my review from negative to positive, their customer service did help my problems and I respect their commitment to helping customers issues. Thank you Altair, would consider buying from again.

We're sorry to hear about your experience. The device you purchased includes a full 1-year manufacturer warranty through Canaan. When you contacted us, you requested a direct refund or for us to replace the unit, which we were unable to provide based on our posted return and warranty policies. However, we did explain that your miner was fully covered under Canaan's manufacturer warranty and provided guidance on how to proceed with a warranty claim. Canaan maintains multiple authorized repair centers around the world, including several in the United States, so customers do not necessarily need to ship hardware overseas for service. In our experience, Canaan has been excellent to work with and has consistently provided professional support and reasonable turnaround times for warranty repairs. We certainly do not sell non-functional devices intentionally, nor do we tell customers "tough luck" when an issue arises. We only sell new unopened boxes. Mining hardware is complex electronic equipment, and while failures can occasionally occur, that is exactly why manufacturer warranties exist. Our team works hard to help customers navigate those warranty processes and get their equipment repaired or replaced as efficiently as possible. We understand your frustration and wish you the best in getting your miner serviced under its warranty coverage. Altair Technology

Fast shipping! Even ordered a part that I forgot the next day and they went ahead and threw it in with my first order so I didn't have to wait forever on my last part!

Did not receive the free Nano3 stands with my order

Hello, We are sorry to hear about this. If you added the dock to your order it should have came with your miner. Sometimes it does ship separately depending on the order size and what is in the order. That being said, If you message our support team on our website, we would be happy to sort out the situation for you and get the stand in the mail for you. Altair Technology
