Kensington Slimblade Trackball Disassembly

Introdução

This trackball is of a very robust construction; I have been using it for my work since 2009.

I appreciate the ball's inertia; crossing the screen only takes a flick. The large buttons allow a great deal of freedom of positioning your fingers. The four buttons are programmable and accept 6 commands.

In normal usage the trackball can get dirty, but the ball and optical sensors are easy to clean with a microfiber cloth. However, as with all mice, the interior cannot be cleaned without disassembly. I recently lost the use of the right click.
