Factory Updates: Weekly Notes from Our Hong Kong Warehouse

Most ASIC hardware vendors tell you nothing about how they operate. We do the opposite. This is where we publish what is actually happening on the floor: how we test units before dispatch, what network conditions mean for your hardware decisions, real operator stories from customers who have scaled with us, and honest breakdowns of the shipping and customs process. Updated weekly. No marketing fluff, no sponsored content, no affiliate agenda.
