New, open box to inspect. This listing is for a ProtoArc EM03 NL Ergonomic Rechargeable Wireless Trackball Mouse in Gray. The item is in brand new, open-box condition, meaning it has never been used, but the original retail packaging has been opened. Expertly sculpted to match the natural contours of your hand, this index-finger-operated trackball provides maximum comfort and promotes a healthy, neutral wrist posture to dramatically reduce arm fatigue during long computing sessions. Because the mouse stays completely stationary while you glide the oversized 44mm smooth rollerball, it acts as an excellent space-saving solution for tight, cluttered workspaces or uneven desk surfaces. This specialized "NL" edition features a sleek profile without distracting RGB light rings, optimizing battery performance for a cleaner, professional look.
Engineered for ultimate productivity, this high-performance mouse features triple-device connectivity that lets you switch seamlessly between three computers or tablets using the included 2.4G wireless USB receiver and two distinct Bluetooth channels. It is equipped with whisper-quiet, silent-click buttons to minimize noise distractions, making it perfect for shared home offices or quiet library settings. You can instantly adapt your tracking speed to your tasks with five built-in, adjustable DPI levels ranging from 200 to 1600 DPI. Powering the device is a high-capacity lithium polymer battery that recharges via a standard USB-C port, delivering up to 60 days of usage on a single charge so you never have to mess with disposable batteries. It offers universal plug-and-play compatibility across Windows, macOS, iPadOS, ChromeOS, and Linux systems.This open-box item comes complete with all its original components from a clean, smoke-free environment.
