PROTOARC EM11 Rechargeable Bluetooth Wireless Vertical Trackball Mouse

Take complete control of your workspace ergonomics and computing productivity with the ProtoArc EM11 Rechargeable Bluetooth Wireless Vertical Trackball Mouse. Masterfully engineered for data entry, office administration, and multi-device multitasking, this advanced right-handed vertical wireless mouse holds your arm at an optimal 58-degree handshake angle. This anatomical layout keeps your hand and wrist in a natural, neutral posture, completely eliminating painful forearm twisting while protecting you from chronic joint fatigue and Carpal Tunnel syndrome.

Featuring a specialized desktop tracking setup, the EM11 handles navigation with three times less hand movement than standard pointing devices, relying on its high-precision 2400 DPI optical tracking sensor to glide seamlessly across expansive monitor screens. Equipped with an integrated 3-device connection framework (dual Bluetooth + 2.4G wireless USB nano receiver), it toggles natively between your PC, tablet, and MacBook at the touch of a button. Completed with quiet-click acoustic micro-switches and a premium Type-C rechargeable battery, it brings total ergonomic luxury to medium-sized hands.

• Anatomical 58° Handshake Angle: Specially sculpted asymmetric vertical frame guides your wrist, arm, and shoulder into a comfortable, neutral alignment to alleviate daily tendon tension.
• 3-Device Multi-System Connection: Pair up to 3 individual hardware setups simultaneously via dual Bluetooth and 2.4GHz wireless channels, switching screens effortlessly with one button.
• 3x Less Hand Movement Strain: High-performance 2400 DPI tracking sensor tracks with ultimate optical precision, letting you navigate large displays with minimum muscular effort.
• Whisper-Quiet Silent Click Switches: Noise-dampened main buttons absorb distracting clicking sounds, making this silent mouse perfect for libraries, shared open offices, and home setups.
• 3-Level Variable DPI Selector: Instantly recalibrate cursor responsiveness across 1000, 1600, and 2400 DPI presets via a dedicated hardware shifter to match your task requirements.
• Integrated Type-C Rechargeable Battery: Houses an eco-friendly 500mAh lithium-ion battery delivering up to 90 days of standby power, recharging quickly using the included Type-C cable.

⚠️ OS Side Button Note: While the core cursor tracking and connectivity systems sync natively across all platforms, please note that the forward and backward side navigation thumb buttons are not compatible with macOS systems.

The ProtoArc EM11 Vertical Mouse is the definitive structural remedy for remote professionals looking to replace traditional flat computer peripherals that cause hand cramping. Standard mice force your forearm bones to cross over into a state of continuous muscle pronation, compressing vital nerves. This masterfully contoured alternative supports your entire palm with an extended wrist rest, keeping your hand fully relaxed even during marathon spreadsheet auditing or typing sessions.

Whether you are matching formulas across wide ledger pages on a Windows PC, scrolling through media timelines on a tablet, or managing emails on an iPad, its stable internal chipset handles inputs seamlessly without lag. It fits cleanly on crowded office desks or public travel trays, reducing tracking fatigue entirely. Wrapped in a sleek, business-style black finish, it represents the ultimate modern toolkit addition for healthy, pain-free desktop performance.
