Perixx PERIMICE-522 Trackball Mouse with Index Finger Control 1.58" Large Trackball, Quiet Click, Programmable Buttons

Index-Finger Trackball Control – Ergonomic trackball design lets you control the cursor with your index and middle fingers while keeping your hand and wrist in a more natural position. Compared with thumb-operated trackballs, index-finger control provides a different range of motion for precise, flexible navigation. Large 1.58-Inch European-Made Trackball – Features a large 1.58-inch (40 mm) trackball manufactured in Europe with a high-quality glossy surface. Integrated particles support accurate sensor tracking for smooth, responsive cursor control during work, browsing, and everyday navigation. All Quiet-Click 6 Buttons – Enjoy a quieter workspace with quiet-click technology across the main left and right buttons as well as the additional side and DPI buttons. Ideal for offices, shared workspaces, home offices, and late-night computer use where minimizing click noise matters. Programmable Buttons Without Software Installation – Customize supported button functions through the Perixx website without installing additional software. Button programming supports Windows, macOS, and Linux, allowing you to personalize controls for a more efficient workflow. 3D-Printing Expansion Dock – Built-in docking slots on the bottom of the mouse support compatible 3D-printed add-on modules, giving makers and advanced users more ways to customize their setup. Compatible 3D-print designs may be available through the Perixx website or 3D-printing communities. 3D-printed accessories are not included. Natural Ergonomic Learning Curve – Switching from a traditional mouse or thumb-operated trackball may require a short adjustment period. Most users become comfortable with the index-finger trackball operation within 1–2 weeks of regular use. Adjustable DPI & Comfort-Focused Design – Choose from 400, 800, 1200, or 2400 DPI for precise, responsive cursor control. The soft rubber-coated surface provides a secure and comfortable grip, while the smooth-scroll wheel enables fluid navigation. A reliable, wired USB connection with an extra-long 5.9 ft (1.8 m) cable offers flexible desk placement. Mouse dimensions: 4.92 × 2.44 × 3.03 inches; weight: 0.35 lb. Wide Compatibility & 12-Month Warranty – Compatible with Windows 7, 8, 10, and 11, macOS 10.12 or later, and Android 4.3 or later.
