BIGtrack 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.
