I have to agree with SCI FI Tech; I find it a little hard to believe that anyone, even computer forensics experts, need to spend $30 on a device that keeps your screen saver from coming active by jiggling your mouse, despite what WiebeTech might claim. However, the story of an inter-office revenge gag on the Mouse Jiggler's product page is funny and makes me think the Mouse Jiggler might make for a pretty fun, if expensive prank gadget.
