The BenQ InstaShow WDC10 was designed to provide a simple, network independent wireless presentation solution that allows a high level of flexibility in conference room settings. No longer are presenters confined to the front of the room or wherever the wired connection dictates. Presentations are easily made from anywhere in the room in three simple steps: Plug-in, Press the button, and Present. Additionally, the InstaShow comes with two transmitter buttons, so switching to another presenter can be done quickly at the press of a button.
