Kensington Wireless USB Presenter Black/Chrome K33373EU

The Wireless Presenter is designed without a laser pointer so it can be used for presentations in locations where lasers are not allowed. With an intuitive 4-button layout, you can easily go forward and back on your PowerPoint® or Keynote® slides, while the other two buttons let you hide your screen and play a slideshow. With a 20m range, you can remain in control of your presentation while you roam the room.
