[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 shaker 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 ensure 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 is required, and there is no need for Bluetooth or additional programs. Easy to use. [7 Dynamic Breathing Lights] Our mouse shaker features 7 dynamic lights that add visual appeal and help make your desk setup more engaging. The lights can be turned on or off freely. The mouse jiggler powers on with lights automatically. Press the light button briefly to cycle through the 7 light colors, and press and hold for 3 seconds to turn off the lights. The mouse jiggler can help keep your computer active and may support various activities such as sports, yoga, dating, working from home, or playing games with kids.
