5.1 Changing Mouse Shells
The mouse comes with two different sized top shells. To change the shell:
- Gently detach the currently installed top shell from the mouse body.

This allows you to modify the mouse's hump height and overall feel for optimal comfort and control.

6. Maintenance
Proper maintenance ensures the longevity and performance of your Xtrfy M42 gaming mouse.
6.1 Cleaning the Mouse
- Disconnect the mouse from your computer before cleaning.
- Use a soft, dry, lint-free cloth to wipe the surface of the mouse.
- For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid harsh chemicals.
- Use compressed air to clear dust from the holes in the shell and around buttons.
6.2 Caring for PTFE Skates
The M42 features 100% PTFE skates for smooth glide. Keep the mouse pad and the underside of the mouse clean to prevent debris from accumulating on the skates, which can affect glide performance. Avoid scratching or damaging the skates.
