A different way to navigate a gaming setup
The Logitech ERGO M575S replaces mouse movement with thumb-operated cursor control. That makes it worth considering for a crowded PC setup, particularly if you want a separate pointing device for desktop navigation rather than another conventional gaming mouse. This review covers the Graphite + Blue Ball configuration and is based on the supplied retailer specifications, not hands-on testing.
The central buying question is whether you want to change how you control the pointer. Bluetooth, an included Logi Bolt receiver and three customizable buttons provide practical conveniences, but they do not establish gaming responsiveness. The strongest specification-based case for this trackball is its reduced need for movement space; its suitability for your preferred games remains a separate question.

Desk fit depends on movement space, not just body size
Logitech describes the M575S as allowing cursor movement without moving your hand. For desk planning, the useful implication is that you do not need to reserve a conventional mouse’s travel area around it. If a keyboard, microphone stand or other equipment leaves only a small pointing-device zone, stationary thumb control could make that layout more workable.
That does not mean the device itself has a negligible footprint. The listing gives dimensions of 4.13 × 3.94 × 5.28 inches without identifying the axes. Those figures should not be treated as a confirmed width-and-depth footprint for a tightly fitted keyboard tray. Leave comfortable access around the unit rather than planning a cutout from these numbers alone.
The listing also promotes use on any surface. That is a manufacturer claim, not a surface test here. The practical distinction is that you manipulate the ball rather than slide the body to steer the pointer. If you intend to retain a conventional mouse for gaming, our gaming mouse pad guide can help you plan that separate movement area.
Three customizable buttons, with important software questions
The supplied feature list specifies three customizable buttons, shortcuts and Smart Actions through Logi Options Plus. It also lists adjustable cursor speed. These tools give the M575S more flexibility than a fixed-function pointing device: assigning frequently used commands could make it useful for browsing, launchers and routine PC tasks between games.
However, three customizable buttons should not be read as a complete button-layout specification. The evidence does not identify every control or explain which assignments are available. It also does not establish onboard profile storage, game-specific profiles or the full range of supported commands. Buyers who depend on a particular binding should verify that workflow rather than assume the software will reproduce a gaming-mouse setup.
Quiet clicks are another advertised feature. That may appeal at a shared desk, but no noise measurements or detailed switch-feel information are supplied. Likewise, cursor-speed adjustment is not evidence of a particular sensor sensitivity range or polling rate. Neither polling rate nor wireless latency is documented here, so there is no basis for promising competitive gaming performance.
Two wireless routes and an AA battery
The M575S supports Bluetooth and the included Logi Bolt USB receiver. That offers a useful connection choice: Bluetooth can avoid dedicating a USB port to the receiver on a compatible host, while the receiver provides another way to connect. The evidence does not describe simultaneous connections, multi-device switching or a wired data mode.
Operating-system versions and the receiver’s connector type are not specified in the supplied material. Check those details against your PC, available ports and software requirements before relying on a particular setup. The presence of Bluetooth alone should not be taken as confirmation that every customization feature works on every Bluetooth-equipped device.
Power comes from an included AA battery, with Logitech advertising up to 18 months of battery life. Treat that as a conditional maximum rather than a replacement schedule: the listing references a battery-life footnote but does not supply its conditions. The included battery is convenient for initial setup, though the evidence provides no rechargeable or charging-cable capability.
Ergonomic promises are not a personal fit guarantee
Logitech promotes a sculpted shape, improved forearm posture and reduced forearm muscle strain, including a quantified reduction claim. The supplied material does not include the underlying test conditions or comparison baseline. Those statements explain the product’s ergonomic positioning but cannot establish how your hand or arm will respond.
Although the listing describes a fit for most hand sizes, it provides no hand-size measurements or detailed handedness guidance. Thumb control also represents a different input habit from moving a conventional mouse. As an editorial consideration, anyone choosing it to address discomfort should assess thumb comfort as well as arm movement, rather than assume that shifting the work automatically resolves the problem. For maintenance, the listing explicitly allows the ball to be ejected for cleaning, but it does not specify a cleaning interval.
Verdict: most persuasive as a space-saving desktop companion
The ERGO M575S offers a clear combination: stationary thumb control, two wireless connection options, three customizable buttons and an included AA battery. It is a plausible companion to a gaming mouse when desk navigation and reduced movement space matter. It is less convincing as a specification-led replacement for a gaming-focused device because latency, polling rate and detailed control behavior remain undocumented. Choose it for the trackball interaction, not an assumption of equivalent gaming performance.
