Manufacturing runs at a stated capacity of 2,000,000 units per month across 147,000 m² of factory floor in Fenggang and Humen, Dongguan, with 2,000 total staff including 100 R&D and 100 QA personnel.

The business model combines direct-to-consumer e-commerce through global and regional websites (serving 35+ countries including China, Russia, Ukraine, Pakistan, Australia, and North America), OEM/ODM custom manufacturing services for partners, and regional distributor networks. Pricing is not publicly disclosed. Revenue derives from hardware sales across consumer, enterprise, and gaming segments. The company maintains ISO 9001, CE, FCC, RoHS, and REACH certifications and operates as a private company with no disclosed funding rounds, management team details, or financial statements.
