Cross-platform or multi-device flexibility was supported by wired, Bluetooth, and 2.4GHz modes, plus evidence of use across Windows, MacBook, work, gaming, and mobile setups.

Cross-platform compatibility is supported by one review noting PC or Mac connectivity through wireless, Bluetooth, or wired modes.

Debounce customization was weak: one reviewer specifically noted the software did not allow bounce-setting adjustment.

DPI range was repeatedly supported by the 42,000 DPI/CPI ceiling and, in some cases, preset or adjustable DPI controls.

The DPI range is broad, commonly cited at 26,000 DPI with configurable stages, giving plenty of sensitivity headroom even if most reviewers did not need the maximum.

Durability over time was mostly positive because of optical-switch lifespan and sturdy build, but one travel-use review reported visible finish scuffing.

Durability over time is only directly criticized in one review, which worried that the thin dongle-cover plate could break easily.

Ecosystem integration was supported through the ROG Omni receiver, single-dongle multi-device pairing, Aura Sync, and compatibility with other ROG peripherals.

Ecosystem integration is strong for Corsair users, with iCUE, multipoint dongle pairing, RGB synchronization, and broader Corsair-device integration.

Ergonomic design was mixed: smaller-handed users found the frame comfortable, while one review said the semi-symmetrical shape gives up some ergonomic specificity.

Ergonomic design is intentionally compact and ambidextrous-leaning, but reviewers note this inclusiveness sacrifices some hand-filling comfort.

Fingertip grip comfort was consistently positive where discussed, with reviewers saying the shape supports fingertip use and keeps fingers naturally placed.

Fingertip grip comfort is one of the mouse's strongest ergonomic themes, especially for small hands and users who prefer compact control.

Firmware reliability evidence is limited but positive, with reviews noting firmware update support for the mouse or checking updates in iCUE.

FPS gaming suitability was strongly supported through esports positioning, Counter-Strike, Valorant, Apex, pro-FPS references, and emphasis on precision.

FPS suitability is strong, with reviewers repeatedly praising fast swiping, flick shots, precision aiming, and competitive Overwatch or shooter use.

Glide smoothness was praised through pure PTFE feet, smooth pad movement, slick slide pads, and positive comments on the included skates.

Glide smoothness is a major strength, with PTFE feet and low weight repeatedly producing smooth, effortless movement.

Grip texture was broadly praised, with reviewers citing ridged sides, grip tape, grippy coating, rubber grips, and textured matte surfaces.

Grip texture is generally praised on the sides, though the smooth top finish attracts fingerprints and can look greasy.

Handedness was a clear limitation: reviewers repeatedly noted side buttons on the left and right-hand-favoring design despite some symmetrical or ambidextrous shaping.

Handedness support is mixed: the body is often described as ambidextrous or nearly so, but side-button placement still favors right-handed use.

Left and right click quality was positive, with tactile, comfortable, and well-implemented main clicks noted in several reviews.

Left and right click quality is divided, with some reviewers praising satisfying main clicks while others found them soft, undefined, loose, or less precise.

Lift-off distance was configurable where mentioned, with onboard or software options for LOD adjustment.

Lift-off control is supported through iCUE settings, with reviewers noting adjustable lift height or calibration options.

Long-session comfort was supported by one review that explicitly connected the shape to extended gaming-session comfort.

Long-session comfort is mixed: several reviewers found it comfortable for hours, but some reported initial fatigue or faster tiring for non-ideal grips.

Macro support was limited because one review said macro settings required the fuller Armoury Crate and Aura Sync software rather than just the lighter utility.

Macro support is well supported in iCUE, with several reviews noting game-specific macros, key assignments, and app-launch actions.

Materials quality was mixed: reviewers cited bio-based nylon and premium-feeling coatings, but also noted a finish that scuffed or held fingerprints.

Materials quality is mixed, with textured sections liked but the smooth or thin plastic top criticized for fingerprints, shine, or a less premium feel.

MMO gaming suitability was lightly supported by one review that included MMORPG games among use cases, but evidence was much thinner than for FPS.
