Through a systematic testing process, we ensure that our mice comply with the requirements of GB/T 18220-2012, "General Specification for Mice Used in Information Technology Equipment." Purchasers are advised to pay particular attention to core indicators such as sensor accuracy and wireless anti-interference capabilities. For esports-grade products, additional verification of specialized parameters such as 1000Hz polling rate and acceleration is required.

We provide professional third-party inspection and factory inspection services to ensure that the final tableware and kitchenware products delivered comply with standards, regulations and target market requirements, avoid disputes due to product quality issues, and improve supply chain management and quality control measures.
