PERIMICE-822IR / 522 Trackball Mouse with Index Finger Control – Wireless or Wired

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.Wireless or Wired, Same Design – Choose the PERIMICE-822IR for 3X multi-device connection (1× 2.4 GHz and 2× Bluetooth; pair once and switch between desktop, laptop, tablet or smartphone – its USB-C port is for charging only), or the PERIMICE-522 for a simple USB plug-and-play connection with nothing to charge. Both share the same shape, trackball and buttons.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 button functions, pointer speed (DPI) and polling rate in your browser with Perixx Console (configure.perixx.com). No software to install; works with Windows, macOS and Linux.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.
