[Upgraded Ultra Slim & Silent Design] Our ultra-thin mouse mover is only 16.5 mm thick and weighs 122g net weight. Built-in smaller and higher-power motors make the device quiet and undetectable. This mouse jiggler keeps your mouse active all the time and prevents your computer screen from locking or going to sleep. The back-and-forth linear motion cannot be detected. (Please make sure the sensor area of your mouse is positioned over the wheel of the mouse mover.) [0.5H-1H-2H-4H] When the mouse mover device rotates, click the timer button to set the countdown from 0.5 hours to 4 hours. Each set of lights represents 30 minutes, 60 minutes, 120 minutes, and 240 minutes. After the countdown ends, the mouse mover turntable stops. [Plug and Play] The mouse jiggler uses a 5V adapter or a computer USB port. No software installation required and no Bluetooth connection needed. Easy to use.

The device automatically powers on the lights when turned on. Short press the light button to switch between 7 light colors, and long press for 3 seconds to turn off the lights. The mouse jiggler can keep your computer active and is suitable for various home and office applications. Ideal for holidays such as Thanksgiving, Mother's Day, Father's Day, Birthday, and Christmas.
