Quality Control
Product quality is the most important part to us. Each product must be tested on a test bench to obtain accurate real-world data and then passed through manual screening. Every product that passes the test has a corresponding certificate of conformity and promises a long shelf life.
We will repeatedly confirm the accuracy of the product with the customer before delivery
