Product introduction

The magnesium-aluminum alloy shell makes the A90 more robust and reliable, while the intensive design makes the A90 easier and more convenient. The internal structure of A90 has been improved more. The whole circuit of A90 adopts a full socket connection, and there is no wiring cable inside to eliminate the quality problems caused by a loose cable. The internal partition board is processed by CNC, which improves the internal heat dissipation, signal shielding and structural stability of A90. The a90 is not only better used but also more durable. Support star chain endurance and China precision.
