Thumb-operated trackball for smooth, precise cursor control on nearly any surface (nominal value: 400 dpi). Use Options software to adjust pointer speed to your liking.

Two connection choices — Bluetooth or the USB receiver — deliver dependable performance with no drop‑offs or lag up to a 33 ft (10m) range. Sustainability details: ERGO M575 plastic parts include post consumer recycled plastic (Graphite/Black: 50%, Off-White: 21%). Packaging uses FSC-certified paper.
