[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 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 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 need to install any software, no Bluetooth or additional programs required. Easy to use.
