Professionals count on Kensington for control of their presentations. With a highly reliable wireless connection and intuitive controls, this presentation pointer allows you to focus on what matters most - making an effective presentation. With a 4-button layout, you can easily go forward and back on your PowerPoint? or Keynote? slides, while the other two buttons offer a screen blackout option and a red laser pointer. The wireless 2.4GHz receiver stores conveniently inside the remote, and since it's uniquely paired, you don't have to worry about device interference.
