The video shows a close-up of a black computer mouse with a blue light on it. The mouse is on a desk, and a person's hand is seen moving it around. The hand appears to be testing the mouse's movement and clicking features. The mouse has a sleek design with a scroll wheel and multiple buttons. The blue light on the mouse is the only source of light in the video, and it stands out against the black color of the mouse. The person's hand is visible throughout the video, and it appears to be that of an adult. The desk on which the mouse is placed is not clearly visible, but it seems to be a standard office desk.
