Our products have been tested continuously for several days, and the test results are the same as the previous products, and they can all work normally. The last time we ordered 3500PCS, we also sent the goods in accordance with the previous product quality standards. When the product is produced in the manufacturing workshop, IPQC inspects the product, and when it is delivered to the warehouse, the quality control OQC inspects it again! None of the products have any problems that you reported to us.
