The BIGtrack Trackball has a 3 inch trackball which makes it the largest trackball available. The large ball requires less fine motor control than a standard trackball and it is ruggedly built. It has a left and a right mouse click button located behind the trackball to avoid unwanted mouse clicks and 2 3.5mm ports for optional switches. You must order the switches separately.
