BIGtrack by Infogrip is a very big, easy-to-use trackball-style mouse. It features a 3-inch yellow ball and has two blue buttons (for left and right mouse clicks) located behind the trackball to avoid unwanted clicks.

• Works on any Windows or Macintosh computer that has a USB or PS/2 port
• Can co-exist with a conventional mouse on the same computer

Ruggedly built. Great for kids, and for adults with mobility or fine motor limitations.
