[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 mouse jiggler quiet and undetectable. This device keeps your mouse active at all times and helps prevent your computer screen from locking or going to sleep. The back-and-forth linear motion is smooth and discreet. (Please ensure the sensor area of your mouse is properly aligned with the spinning 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 indicator light 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 works with a 5V adapter or a computer USB port. No software installation is required, and there are no Bluetooth connections or additional programs needed. Simple and easy to use. [7 Dynamic Breathing Lights] This mouse shaker features 7 dynamic LED lights that add a stylish touch to your desk. The lights can be turned on or off freely.
