Query: a GREAT smart pointer-presenter

This one really exceeds my needs. It is really 3 devices in one 3 inch tall product.1. red laser pointer, similar to others2. remote Powerpoint controller, including front, back, black, restart the slide deck3. remote handheld mouse if ppt/mouse switch is set to 'mouse'Easy set up. No drivers, it just works right out of the box. Red color makes it easy to spot in a dim room.
