About this item
- Adjustable Tilt Angle: With its customizable hinge, you can easily set the trackball to a flat 0° or a tilted 15° position. This ergonomic adjustment helps maintain a natural hand posture, reducing strain and providing personalized comfort throughout the day.
- Precise Trackball Control: Navigate efficiently without moving your wrist—simply roll the trackball for smooth, accurate cursor control. Ideal for tight or cluttered workspaces, it minimizes fatigue and maximizes productivity even in limited desk areas.
- Multi-Device Connectivity: Seamlessly connect via 2.4GHz wireless or Bluetooth and switch between devices with one button. Offers broad compatibility across systems (note: forward/backward buttons are not compatible with Mac OS).
- USB-C Rechargeable with Extended Standby: Features a convenient USB-C charging port and an impressive 90-day standby time on a full charge. Enjoy long-lasting performance with minimal need for recharging, ensuring reliable use day after day.
- Quiet Clicks & Adjustable DPI: Equipped with quiet-touch buttons, perfect for late-night work without disturbing others. Five adjustable DPI settings (200/400/800/1200/1600) allow you to fine-tune cursor speed, helping you adapt smoothly to trackball use and match your workflow precision.
- Health Tip: Like any ergonomic tool, trackball mice require a short learning curve. Unlike traditional mice, they keep your wrist stable – a more natural motion that reduces pressure and fatigue. Most users adapt within 1–2 weeks. Experiment with hand positions to find your comfort. Our goal: healthier, pain‑free use for years
- Cleaning Tips: After prolonged use, any trackball will accumulate dust—this is normal. If you experience issues such as stickiness, unsmooth or lack of precision, please clean the ball and the three white rollers firstly to resolve the problem.
