ELECOM Ergonomic Comfort Design Trackball IST Wired USB-A Connection

Bottom line: The ELECOM Ergonomic Comfort Design Trackball IST Wired USB-A Connection ($57.33 on Amazon as of 2026-10-06): Steel roller bearing rolls the 36mm ball with near-zero friction; main trade-off: wired USB-A only, so no Bluetooth or wireless dongle option.
