There are five hollow plastic posts that must be pushed through from the bottom, and each has two small tabs holding it in place. The RollerMouse Pro2 by Contour Design is a central pointing device which in lieu of a traditional mouse uses a rollerbar just below the space bar on the keyboard.

Again, this is just my impression, not the result of a scientific experiment. When working in Pro Mouse mode, which is the default setting, you can choose between or dpi as the cursor speed. Another good example is the rollerbar tension control.
