Logitech Wireless Presenter R800 PowerPoint Clicker with Green Laser

The brilliant green laser pointer is powerful and easy to see, even on LCD and plasma displays and in brightly lit rooms.
The LCD display with timer lets you manage your time with silent, vibrating alerts and controls that are easy to set and adjust–-you’ll focus on your presentation, not the clock.
With a range of up to 100 feet (30 meters), you can enjoy the freedom to move around the room and mingle with your audience for greater impact. A reception-level indicator ensures you don’t wander too far.
The intuitive slideshow controls help you navigate through your presentation with confidence. Buttons are easy to find by touch. The smooth contours feel great in your hand. You’ll be in control from the first slide to the last.
A storable plug-and-play wireless receiver makes it simple to get started—just plug the receiver into a USB port and use it right away. There’s no software to install. When you’re through, the receiver stores inside the presenter to make packing up easy.
