This is a trackpad (touchpad) compatible with Bluetooth, etc., that can be used with Windows 11. It supports 3-finger and 4-finger gestures. I am selling it because I am changing my setup. Operation has been confirmed. *Regarding the product specifications, clicking is not possible by pressing down on the pad (clicking is determined by tapping the pad). This may not be suitable for those who prefer pressing down for clicks. *For other details, please refer to the instruction manual. It was convenient for zooming in and out. Since this is a used item, please refrain from purchasing if you are extremely concerned about the condition.
