Each Protrack is carefully assembled using the highest quality components and a superior build process. Stainless steel shafts and precisely engineered steel bearings support a 60mm diameter high-mass ball to provide you with smooth running and precise operation - you can feel the difference!
Recent research has indicated that a trackerball can be less stressful on the user than other cursor control systems. The large ball design, low tracking force and easy to use buttons, featured on the Protrack, provide the user with an effective means of cursor control with a minimum of stress.
