I had another excellent experience with AltairTech, especially with Kris. I ran into a technical issue with a newly released miner I purchased from them, and Kris took the problem seriously from the beginning. He reviewed the information I provided, worked directly with the manufacturer, kept me updated, and even offered me a beta firmware to try while an official fix was being prepared. I installed the beta firmware and the issue was resolved. This is exactly the kind of customer service I appreciate: responsive, knowledgeable, and focused on actually solving the problem instead of just sending canned support responses. This level of support is what will keep me coming back. They’ve definitely earned my future business. Highly recommended.

Thank you for sharing your experience! We’re happy Kris was able to help troubleshoot the issue, coordinate with the manufacturer, and keep you updated throughout the process. New miner releases can occasionally come with unexpected firmware challenges, but we always do our best to help customers find a real solution. We appreciate your continued business and recommendation. AltairTech.io

Wow super fast delivery by UPS and excellent price for USA stock BM1370 BC chips. Now I just have to work up the courage to strip down my NQA++ and replace the one blown chip that I previously had replaced by a weaker version so I could get it running ASAP. Fun times!
