This remote / mouse is convenient (especially for presentations or you just have a large screen): Plug and play (tested with Vista and Windows 7), fairly intuitive, we quickly mark among the buttons; good value for money (virtually the same price as a single mouse without remote control). Its only flaw is missing a start / stop button! It is better to remove the batteries during transport to avoid draining too fast! Too bad, with the on / off button would have been fine.
