The only direct stability feedback says larger keys are slightly rattly, but still remain fairly stable overall.
Stability depends on build choices; one review praised reduced wobble, while another noticed play and wiggle in its plate and switch setup.
Latency and response are consistently praised. Reviews mention fast in-game response and 1ms-class performance language for the keyboard or its switch behavior.
Core software exposes very low configurable input latency, with one reviewer noting it can be set as low as 2 milliseconds.
The lineup is offered in 65%, 75%, and 100% layouts.
Legend visibility is mixed. Main legends can look clean, but several reviews criticize secondary legends that do not light up or are unevenly lit on some versions.
Legend visibility depends on the chosen caps; one review notes the selected keycaps lit the legends sufficiently.
Macro support is present and useful across the reviews, though the software experience for setting macros is not praised equally by everyone.
Reviews confirm users can assign modifier-based or recorded macro actions to keys.
Materials quality is a standout, driven by repeated praise for the aluminum or aluminum-magnesium top plate and the premium feel it gives the keyboard.
The full aluminum build is a standout part of the product's premium feel.
Media controls are functional rather than premium. The keyboard offers shortcut-based media control, but several reviewers miss dedicated buttons.
The knob supports some media-related reassignment attempts, but one reviewer could not get their desired play or pause function working.
Noise level is one of the main tradeoffs. Some switch versions are fairly controlled, but GX Blue can be loud enough to bother nearby people.
One reviewer called it one of the quietest boards they had tested in that specific configuration.
Reviews mention onboard memory or onboard profile storage for saving settings directly to the keyboard.
The USB passthrough is generally useful for mice, charging, or extra peripherals, but multiple reviews wish it were faster than USB 2.0.
Several reviews explicitly mention per-key lighting control, including per-key color selection and per-key RGB customization.
One review explicitly cites a 1ms report rate as part of the G512's update set, supporting strong polling-rate performance.
Multiple reviews confirm wired polling up to 8000Hz and describe that high rate as working without issue.
Portability is weak. Reviews repeatedly note that the keyboard is heavy, which helps desk stability but makes it less portable.
Heavy aluminum builds hurt portability and make the board harder to move around.
The keyboard supports game-specific or software-managed profiles, and reviews also mention saved profile handling.
Core allows users to save and switch between multiple profiles.
Rapid Trigger is explicitly supported and highlighted as a core Hall-effect gaming feature.
Reliability evidence is mixed. One review describes it as a solid long-term keyboard, while another reports a failed passthrough/static issue on an early unit.
One review reported a serious failure involving repeated keys and a dead board before replacement.
RGB customization is one of the G512's biggest strengths. Reviews mention presets, custom effects, per-game lighting behavior, and broad software control.
Core software lets users program RGB lighting behavior and effects.
RGB lighting quality is generally praised for looking good and staying vivid without feeling overly harsh, though one review says GX Blue models have less even lighting than Romer-G versions.
RGB lighting is described as generous and strong-looking, with good diffusion and visible accent lighting around the board.
