To keep us in the forefront of this field, we reinvest 40% of our annual sales revenue into R&D. We have 10 R&D engineers with eight years experience in this line. They dedicate themselves to new product designs, and they also welcome your specifications. With the help of our own molding workshop, we can provide samples within two months.

To ensure every piece you receive is defect free, we source chipsets from Hong Kong SAR and Taiwan area, and other components from suppliers with whom we cooperated for over eight years. In addition, we assign three QC staff in each production line. All our products meet CE, FCC and RoHS standards.
