Excellent tool for presentations

The Logitech R 800 fits comfortably in your hand, the green laser pointer produces a highly visible light spot and is to my mind more convenient for presenters and audiences as a red laser. The timer Vibration setting helps temporally terminated presentations comply with the prescribed time. The presenter can also move thanks to the 100-foot-range time away from the computer, which helps break up the exclusively frontal lectures delivered in most cases. Overall, an excellent tool.
