LS&S Big Track Mouse Ball
This Trackball Mouse is large, bold and very easy to work with. The BIGtrack is an easy and effective way to move the mouse cursor across the screen with its 3" diameter trackball. It has a left and a right mouse click button located behind the trackball to avoid unwanted and unexpected mouse clicks.
The large yellow ball has great high contrast visibility and requires less fine motor control than a standard trackball, making it great for both low vision and/or those lacking fine motor skills. It's also a great trackball style mouse for kids.
