This ultimate 6-button 2.4 GHz wireless controller acts as your presenter, trackball, laser pointer and desktop mouse all in one device. The built-in sensor automatically switches to presenter mode when picked up, thus letting you fully concentrate on your work. It is ideal for controlling presentations, browsing the internet and playing your movies/music with a wireless freedom of up to 15 meters. In mouse mode, the trackball works as a scroll wheel. Use the desktop cradle to charge the presenter mouse via USB in your home/office. The USB charging cable is included for mobile use; no power adapter and travel conversion plugs needed.
