Logitech Professional Presenter R800 gives you powerful control for high-impact presentations. The brilliant green laser pointer is easy to see, even on flat panel displays, projection screens, and in brightly lit rooms. Manage your time with silent, vibrating alerts and controls that are easy to set and adjust. Move about for greater impact, with a range of up to 100 feet (30 meters) you can cover every corner of the room. Navigate through your presentation with confidence thanks to intuitive slideshow controls you can find easily by touch. A storable plug-and-play wireless receiver makes it simple to get started—there’s no software to install. And when you’re through, the receiver stores inside the presenter to make packing up easy.
