CONTOUR ROLLER MOUSE
RollerMouse works well in compact spaces and offers different styles for users with small to large hands. RollerMouse products provide palm support and allow you to maneuver your PC or Mac cursor with just your fingers, eliminating the need for you to hold your hand against gravity. That can reduce tremors. RollerMouse is ideal for use with mountable keyboard trays. $254.00
