When your mouse keeps running into the keyboard, another mat may not solve the problem. The black, silver-ball Logitech ERGO M575S stays in place while your right thumb moves the cursor. That makes it a genuinely different option for a narrow workstation, rather than just another mouse with a softer grip.
Trade sweeping movements for thumb control
The stationary body needs a place to sit, but no lane for repeated mouse strokes. The photographs show the ball beside the main buttons: your thumb steers while your fingers click and scroll. That separation can suit a tight setup, although it takes practice if you have always moved the whole mouse.
Do not buy it expecting automatic precision or a cure for discomfort. Thumb control must feel acceptable to you, and this is a right-handed design. If your thumb is already uncomfortable, a finger-operated trackball or a different workstation arrangement may be a better question to explore.
Remember the small maintenance jobs
The removable-ball photograph is useful because dust can affect tracking. Follow Logitech’s cleaning instructions for the ball and supporting surfaces rather than spraying liquid into the socket. This version uses an AA battery and offers Bluetooth or the included Logi Bolt receiver; confirm your chosen connection and computer compatibility.
Choose M575S for a stationary pointer and a less crowded working surface. Skip it if you dislike relearning control or need left-handed operation. Match the listing carefully: this guide concerns the M575S with a black body and silver ball, not the original M575 or a blue-ball colourway.
