ERGO M575S Wireless

The Logitech ERGO M575S Wireless trackball, MPN 910-007030, comes in Off-White with a blue ball. Thumb control moves the cursor while your arm stays still, so it can suit a compact or busy desk.

Its sculpted ergonomic shape supports the hand, and Logitech says it works on any surface. Quiet clicks are 80% quieter than on the ERGO M575, according to Logitech.

Customize three controls: Back, Forward and the scroll wheel’s middle click. Adjust cursor speed in Logi Options+ to set pointer movement for everyday computer work.

This model combines thumb-operated cursor control with compact placement for routine desk use.
