The new Fellowes GelMouse is the first and only scrolling mouse with a patented Gel insert on the top surface for increased comfort, and a PS/2 to USB interface. The Fellowes GelMouse is a fully functional 3 button scrolling mouse. The software provided with the GelMouse allows for full button programmability and scrolling customization. The Fellowes GelMouse can move seamlessly between a traditional PS/2 port and a USB port. This provides unparalleled flexibility in peripheral usage by allowing a user to free up a PS/2 port for other devices (this is particularly useful for laptop users). This mouse has the ultimate combination of ergonomic design for comfort, and technical design for easy use and flexible setups.
