Before you rebuild your mouse.
Straight answers on donor hardware, installation, biometric calibration, and fit.
We engineer custom biometric shells, not the electronic circuit boards. To build an ApexShell, you need the internal motherboard (PCB) of a compatible mouse. You simply unscrew the base of your Logitech GPX2 or G305, remove the motherboard, and drop it into our custom 3D-printed chassis.
