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. Automatically simulates small, infrequent mouse movements to prevent screen savers and sleep modes from activating. You can continue to work without interference from the MJ-1.
