Does Your Wrist Ache After a Long Day at the Computer?

Hours of clicking, scrolling, and dragging with a flat mouse puts your wrist in an unnatural position — twisted, strained, and slowly building up tension that turns into pain. Carpal tunnel, wrist fatigue, and repetitive strain injuries are real consequences of using the wrong mouse for too long. And most people don't realize the damage is happening until it's already affecting their work and their life.

The ProtoArc EM11 Ergonomic Vertical Mouse was designed to fix this. The vertical orientation keeps your wrist in a natural handshake position, dramatically reducing strain and fatigue. Connect to 3 devices simultaneously, adjust DPI for precision control, and work all day — comfortably.

The Natural Position Your Wrist Has Been Waiting For

A vertical mouse holds your hand in the same position as a handshake — thumb up, palm facing inward. This is the natural resting position for your forearm and wrist, and it eliminates the pronation (inward rotation) that causes strain with traditional flat mice. Users consistently report reduced wrist pain, less fatigue, and the ability to work longer without discomfort after switching to a vertical design.

Precision Control for Work and Play

Three adjustable DPI levels — 1000, 1600, and 2400 — let you dial in the exact sensitivity you need. Low DPI for precise design work and detailed editing. High DPI for fast navigation across large screens. Switch between them instantly with a single button press, without interrupting what you're doing.

• Vertical ergonomic design — natural handshake position reduces wrist strain
• 3-device multi-connect — Bluetooth + USB receiver, switch instantly
• 3-level DPI (1000/1600/2400) — precision control for any task
• Whisper-quiet clicking — silent operation for shared workspaces
• USB-C rechargeable — 500mAh battery, fast charging, no disposable batteries

Silent. Wireless. Always Ready.

The whisper-quiet click mechanism keeps your workspace peaceful — no disruptive clicking during meetings, calls, or shared office environments. The USB-C rechargeable 500mAh battery charges quickly and lasts through long work sessions. No AA batteries to replace, no running out of power mid-project. Just plug in, charge up, and get back to work.

Built for the Modern Multi-Device Workflow

Whether you're a remote worker juggling a laptop and desktop, a designer switching between a workstation and a drawing tablet, or a gamer who uses multiple setups — the 3-device multi-connect capability means this mouse moves with you seamlessly. One mouse. Three devices. Zero friction.
