ProtoArc EM11 Pro Ergonomic Mouse for Large Hands, Side Scroll, Black

Perfect Fit for Large Hands: Designed for hand lengths of 19.0–21.5 cm (7.5–8.5″”), the larger contoured shape gives your palm more complete support instead of forcing your fingers into a cramped grip. The vertical design keeps your hand and forearm in a more natural position, making it easier to stay comfortable through long hours of emails, spreadsheets, meetings, and everyday office work. For the best fit, please measure your hand before ordering
Seamless Side Scrolling for Wide Workspaces: Perfect for navigating wide Excel sheets, video editing timelines, and long documents. Effortlessly glide left and right using the side scroll wheel—no more dragging the bottom scroll bar. Keep your hand in place, save seconds on every swipe, and stay focused on your work without breaking your flow.
Browser-Based Button Customization: No software download or installation required. Use the browser-based customization tool to configure 6 buttons, adjust DPI, and assign frequently used commands such as copy, paste or other shortcuts. Whether you spend your day processing documents, managing spreadsheets, browsing webpages, or switching between repetitive tasks, commonly used actions can stay closer to your fingertips. The side scroll wheel can also be customized
Ergonomic Vertical Design for Long Hours at Your Desk: Unlike a traditional flat mouse that can keep your forearm rotated for extended periods, the vertical shape encourages a more natural handshake-style position for your wrist and forearm. This can help reduce wrist twisting and everyday strain during long computer sessions, making it a practical choice for home offices, corporate workstations, and anyone who spends several hours a day using a mouse. For first-time users, keep your palm relaxed and allow time to develop a natural grip
Switch Between 3 Devices Without Switching Mice: Connect up to three devices through two Bluetooth 5.0 channels and one 2.4 GHz USB-A receiver. Move from your work laptop to a personal computer or tablet with a simple device switch instead of reconnecting or keeping multiple mice on your desk. Ideal for hybrid workers, dual-computer setups, and home offices where multiple devices are used throughout the day. Compatible with Windows 8/10 or later, macOS 10.12 or later, and Android 4.3 or later
Adjustable up to 7200 DPI for Different Work Tasks: Choose the cursor speed and precision that fits the task, with adjustable sensitivity up to 7200 DPI. Use a lower setting when precise control matters, then increase the DPI when moving quickly across large monitors or multi-screen workspaces. Combined with forward and back buttons, it helps make browsing, document review, spreadsheet work, and everyday multitasking faster and more intuitive
Rechargeable Battery for a Cleaner Desktop Setup: A built-in 500mAh rechargeable lithium-ion battery eliminates the need to regularly replace disposable batteries. Simply recharge the mouse with the included USB Type-C cable, making it more convenient for everyday desk use and helping keep spare batteries out of your workspace. Please note that the included Type-C cable is for charging only
Give Yourself Time to Adjust to a Vertical Mouse: A vertical mouse uses a different hand position from a traditional mouse, so the grip may feel unfamiliar at first. We recommend using it consistently for approximately 1–2 weeks while keeping your hand relaxed. As your hand becomes familiar with the shape and button positions, navigation and everyday movements can begin to feel more natural and comfortable
