## Description

desertcart.com: ProtoArc EM01 NL Wireless Trackball Mouse, Rechargeable Thumb Control, Gray | 0/20° Adjustable Angle to Reduce Fatigue, Triple-Device Bluetooth & 2.4G USB-A for Office Use, Silent Click, Easy to Clean : Electronics

## Features

- 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: Every trackball collects dust—it's normal. Clean the ball and 3 white rollers after long use. Otherwise, accuracy and smoothness drop, especially at 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

A: 1. After prolonged use, any trackball will acumulate dust-this s normal Please dean the ball and the three white rollers fis, then use t as usual. 2. Low battery power can also cause lag.
