This BIG 3" trackball is ideal for users who don't have the fine motor skills required by a mouse. BIGtrack doesn't require control with the fingertips - a swipe at the ball and the buttons works just as well. The left and right mouse click buttons are positioned to help prevent unwanted clicks.

BIGtrack has these great features:

• Suitable for the desktop or your lap.

• Withstands rough handling.

• No need for fine motor skills.

• Two big mouse buttons.

• High contrast colors.

BIGtrack is suitable for Windows and Mac, and for USB and PS2. Just plug it in and you're away! It also allows for a second mouse to be connected simultaneously.
