Turn off the mouse before beginning disassembly.

Flip the mouse over so the sensor and power switch are facing you.

Insert a plastic spudger between each slider and the plastic mouse base. Pry the adhesive slider off of the base to reveal the screw wells.

A careful amount of heat applied directly to the slider before removal can help ensure they are reusable.

The mouse sliders will likely be unusable after removing them, they will need to be replaced.
