The hardware-based Mouse Jiggler prevents your computer from going to sleep while you work or play. This plug-and-use USB device comes in three versions and creates constant mouse activity so your computer won't go idle and trigger screen savers or sleep mode-eliminating the need to log in repeatedly. The MJ-3 is programmable, making it ideal for repetitive IT or gaming tasks. You can create customized scripts with programmed mouse movement, mouse clicks, and keystrokes. The smaller size of the MJ-3 keeps it out of the way and is unobtrusive when installed.
