## Features

- Ergonomic Design for Natural Grip: The vertical design of a 62 degree tilt and natural handshake can perfectly fit the palm of your hand, keeping your arms and wrists in a relaxed state, so that you won't feel tired after a day of work
- Bluetooth & 2.4G Wireless Connection：PLUG and PLAY. This trackball mouse has triple connection modes(2.4G+BT 5.1+BT 3.0). You can control three devices at the same time, switch freely between Android, tablet and Mac with just one button. Note: all the buttons are non-programmable and the backward forward buttons are not compatible with Mac OS system
- Thumb Trackball Mouse: Equipped with a smooth trackball, move your cursor with your thumb movement instead of moving your wrist and arm. It will effectively reduce fatigue and strain for your wrist and arm. Not only work on flat surfaces, but also on your leg, sofa and other surfaces as well, especially in a narrow space, such as the messy desktop
- Rechargeable & Quiet Clicking: The vertical trackball mouse equipped with a build-in rechargeable battery, could be recharged easily with the included USB-C cable. Please remember to turn it off if you do not use it for a long time. Smooth frosted surface and quiet clicks can bring a better user experience and free your worry about bothering others and keep you stay focused while working
- Wide Compatibility & Adjustable DPI: This vertical rollerball mouse is suitable for laptop/PC/notebook/tablet/Macbook/ipad/iPhone. It is compatible with Windows, Android, Mac OS etc. 5 DPI levels (200/400/800/1200/1600 DPI) allows you to change the cursor sensitivity easily for more precise tracking
- After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure that the trackball is always smooth. Note: When the computer is just started or a large application is running, it may also cause the trackball to not run smoothly
- Warm Tips: Since it takes a learning curve to get used to the control method when using our trackball mouse for the first time, it may cause inconvenience to your mouse grip, you can experiment with different hand positions to find what is most comfortable for you. We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort
