This is a trackball, not a mouse.

The upper left button, which is the hardest to use, is middle click by default. The upper right, which the ring finger naturally rests near, defaults to Back. This can be particularly annoying as the Back button is easy to brush when moving hands between keyboard and mouse.

When using the mouse for long duration's the sweat from the users hands can make the rubber side grips slippery.
