ProtoArc EM01 NL Wireless Trackball Mouse, Thumb Control, Purple

Adjustable Trackball Comfort: The 0-20° hinge lets you set the trackball angle to match your hand position, supporting a more natural grip through long work sessions
Thumb-Control Precision: Navigate documents and web pages by moving the thumb trackball instead of your whole arm, making it easier to work on crowded desks, couches, or beds
3-Device Wireless Control: Bluetooth and 2.4G wireless modes let you connect up to three devices and switch between PC, laptop, and tablet with one button
Rechargeable 5-DPI Tracking: The built-in rechargeable battery avoids disposable battery swaps, while 200/400/800/1200/1600 DPI levels adjust cursor speed for different tasks
Quiet Shared-Space Clicks: Quiet left and right clicks and a frosted surface support focused work in offices or home spaces; scroll wheel and side buttons are not silent
Easy Trackball Maintenance: Clean the trackball and three white rollers after extended use to help keep movement smooth, especially after startup or heavy app loading
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
