Our company enforces a short idle period before they invoke a password protected screen saver. During presentations I used to have to either repeatedly unlock the screen or give someone my password (clearly not an ideal solution). The Mouse Jiggler has made my presentation so much more professional and easier without the screen saver interruptions.One word of advice, go with the slow version of the Mouse Jiggler. I found the fast version is more like a practical joke because it makes the pointer scroll wildly across the screen.
