Selected Materials, Proven
Long-Term Durability.

For an exterior surface, we only use the best metal or ABS plastic with best finishing. An additional shielding layer is also applied in order to avoid interference more efficiently and to allow for longer service life.

For an interior structure, there will be no cutting corners, but instead there will be a full aluminum board gutter to prevent internal signal crosstalk, allowing for better communication.

For the core, we utilize the industry-leading ATMEL/STM PCB single chip, brand new SMD and spare parts for better quality.

By no means will we compromise on quality.

Meticulous Workmanship,
Seamless Quality.

Paying attention to every detail, we will craft our products with great care.

Rugged powder-coated casting craftsmanship allows for better heat dissipation, fewer signal "spill-out". Signal failure is not an option.

Flawless appearance with delicate line cutting, no scratch, no flash. You will feel the superior quality once you lay your finger on our product.
