When you use the trackball mouse for a period of time, you need to clean the trackball and inside the hole with a soft cloth to ensure that the trackball is always smooth.

The vertical design of a 62 degrees tilt and natural handshake can perfectly fit the palm of your hand, keeping your arms and wrists in a relaxed state.

Adjust cursor movement speed for superior and accuracy control by pressing the DPI button(200/400/800/1200/1600).

Built-in 500mAh lithium battery, easily charge the mouse with the included USB C charging cable anytime anywhere.

You can use it on a narrow office desktop without moving the mouse.
