When I started doing presentations with PowerPoint I quickly found a obstacle to my productivity. Being tethered to the laptop just to advance slides was restricting my style.The option of having a remote unit that let me walk around would be a major improvement was my reasoning and ultimately the catalyst that would lead me into buying this little Targus wireless multimedia presenter (or laser presenter). The unit is USB powered (no need for external power). The pocket-size remote transmitter runs on one AAA battery and has a range of 30 feet. Opposing <> buttons let me to go back or forward through my presentation. The base button blanks the screen or displays the images. A round red center button powers a built-in laser pointer.

Simple in design,yet robust in features, this presenter does what I need.Effectively The on-off module is black, The laser pointer is adequate for a reflective screen. It is not robust enough for a wall whiteboard.
