Altair has been my go to for building out my small home-based Bitcoin mining farm. I appreciate the high level of customer service I've gotten. It's comforting to know they are U.S. based and available via chat. Shipping is fast and reliable.

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
