The smoothness and low resistance of the large ball allows you to control the mouse cursor with the palm of your hand or with one or more fingers. It includes three large buttons, USB connection and an accessory to make the use more comfortable. It also has non-slip so it won't slide during use. It is robust and resistant and is prepared for intensive use.
