This wireless presenter is designed without a laser pointer, so it can be used in places where lasers are not permitted. The intuitive 4-button layout allows you to easily scroll back and forth through PowerPoint® or Keynote® slides, while the other two buttons allow you to dim the screen or start a slide show. The 20-meter range allows you to move freely during your presentation. The wireless USB receiver can be stored in the presenter so it won t get lost. Plug & Play 2.4GHz wireless connection for quick and easy setup. Compatibility: Windows® 10, 8.1, 8, 7 and macOS®.
