XO MQA Dongle - Like a work of art

The XO MQA Dongle uses a high-density aluminum alloy shell, which is integrally formed with a typical 5-axis CNC high process. For the first time, the etched technology is used on both sides of the XO MQA Dongle. With Hidizs initials - "H" as the design element, the micron-level complex and meticulous metal processing is carried out. Etch a number of "H", end to end, in the shape of a net hollow. The XO MQA Dongle has built-in RGB LED light tubes, and the light changes and staggers, scattered from the countless "H".
