Ergonomic Wireless Trackball Mouse, Rechargeable Adjustable 0°/18° Angle

• Ergonomic Adjustable Angle: 0° or 18° adjustable ergonomic tilt lets you choose a natural handshake position. The 18° angle follows the wrist’s natural resting posture, helping reduce wrist and forearm strain during long hours of work, study, or computer use
• Thumb Trackball Control: Smooth thumb-operated trackball allows precise cursor control without moving your arm across the desk. Reduces repetitive wrist and shoulder movement, making it ideal for small desks, limited spaces, and long daily use
• 3 Device Wireless Switching: Connect up to three devices via dual Bluetooth modes and a 2.4G USB receiver. Switch instantly between your PC, laptop, or tablet with one button. Stable, lag-free wireless connection up to 33 ft (10 m)
• Quiet Clicks & Adjustable DPI: 5 adjustable DPI levels from 800 to 4800 let you match cursor speed to different tasks and screens. Ultra-quiet buttons with up to 95% reduced click noise keep you focused in offices or shared workspaces
• Rechargeable with Backlight: Built-in rechargeable battery with USB-C charging eliminates disposable batteries. Soft ambient backlight can be turned on or off as needed. Compatible with Windows, macOS, Android, and ChromeOS. USB receiver stores neatly in the base
• Recommended Mouse for Students: As an ideal present for students during the back-to-school season, the ergonomic mouse not only improves learning efficiency, but is also a thoughtful and practical present that is an excellent choice for yourself or your relatives and friends
• Warm Tips: If you are using a trackball mouse for the first time, it may take some time to get used to its operation. We recommend that you spend 1-2 weeks to adapt, as many users find that this helps reduce the pressure and pain on the wrist caused by long-term use of the mouse and improves comfort
• You can download the driver by following the steps in the instruction manual to customize the mouse settings and fine-tune them to better suit your personal mouse preferences. (Note: This driver is not compatible with Mac OS.)
