1. Mouse Movement: The device simulates mouse movement to help prevent your PC from entering screen lock or sleep mode. The scroll wheel rotates intermittently with brief pauses, helping keep your computer active during work or gameplay, allowing you to return to your tasks without interruption. 2. Built-in Silent Operation: The scroll wheel uses a non-contact mechanism and is supported by silicone pads for stability and vibration reduction, minimizing noise and preventing disturbance to your workspace. The design includes dynamic LED lighting that alternates between breathing and flowing effects, adding ambient lighting to your environment. 3. Customizable Timer Function: The timer is disabled by default, indicated by no illuminated green LED. Press the button briefly to select a timing interval: one LED light for 0.5 hours, two for 1 hour, three for 2 hours, and four for 4 hours. When all green LEDs are off, the timer is turned off. 4. Multi-color LED Lighting: Offers 9 selectable LED lighting modes. By default, lights operate in a gradient breathing pattern. Short presses cycle through red, green, blue, yellow, cyan, and pink. A long press turns off the lights. The green timer indicator remains lit when a timer is active. 5. Plug-and-Play Compatibility: No software or drivers required. Compatible with most optical mice and supports Windows, macOS, Linux, and Android systems. Powered via USB port from a PC, laptop, hub, docking station, or USB charger.
