## Features

- How It Works：Read Before Use: Unlike a regular mouse that you slide across your desk, this trackball mouse stays completely stationary. You control the cursor by rolling the ball with your thumb or finger. The mouse itself does not move — only the ball rotates to move the cursor on screen. 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.
- Ergonomic Design for Long Work Sessions: The thumb-controlled trackball design reduces wrist pain and repeated arm movement during long office work and home office use. Unique adjustable hinge allows you to customize the trackball angle from 0 to 20 degrees according to your needs, helping create a more comfortable desktop workflow in Long-hour desk setup
- Precise Rollerball Mouse for Productivity: ProtoArc trackball mouse allows smooth and accurate tracking for spreadsheets, coding, creative work, and multitasking(Note: Dirt on the trackball, a device that has just been turned on, or running large applications may cause the mouse to operate less smoothly and with reduced accuracy)
- Rechargeable & Adjustable DPI: The wireless Trackball Mouse has a rechargeable battery. Just charge it and keep working. Please remember to turn it off if you do not use it for a long time. With 5 adjustable DPI levels (200/400/800/1200/1600) allows you to change the cursor sensitivity easily and track more smoothly
- Ideal for Small Desk Setups – Unlike traditional mice that require large movement areas, the stationary trackball design works efficiently in compact desks, shared workspaces, and minimalist desk setups
- Triple Connection Modes: This trackball mouse connect up to 3 devices via bluetooth and 2.4G wireless, making it easy to switch between iMac, MacBook, Windows PC, and iPad setups for productivity-focused users
