Build quality is one of the clearest strengths. Reviewers repeatedly call the keyboard sturdy, rock solid, and more premium than its price might suggest.
Most reviews describe the board as solid or well built for the price, but there are conflicting impressions because some reviewers still report flex or only average refinement.
Cable feedback is mixed. Some reviewers like the sturdy braided build or routing options, while others call it thick, unwieldy, or wish it were detachable.

Keycap feedback is mixed but decent. Some reviews praise the texture and smooth finish, while others call the ABS caps average and note that shine can develop over time.
The PBT double-shot caps are usually praised for feel and longevity, but one reviewer criticizes overall cap quality and inconsistent thinner legends.
The keys are repeatedly described as responsive, with quick registration, light presses, and precise input that supports gaming well.
Reviewers describe the switches as responsive and say the board supports quicker typing and fast-paced play.
One review specifically says the key spacing feels spot on and required no adjustment period.
One reviewer dislikes the compressed layout because the arrow keys are harder to find by feel.
The only direct stability feedback says larger keys are slightly rattly, but still remain fairly stable overall.
Larger stabilized keys are described as free from rattle.
Latency and response are consistently praised. Reviews mention fast in-game response and 1ms-class performance language for the keyboard or its switch behavior.
Wireless 2.4GHz is described as low latency, and wired mode is said to deliver minimal latency.
The board is consistently described as a compact 96% or 90% layout, though one reviewer personally prefers a proper full-size layout.
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.
One review praises the legends as sharp and visible, while another says thinner legends look inconsistent.
Macro support is present and useful across the reviews, though the software experience for setting macros is not praised equally by everyone.
Reviews say macro recording is supported and simple to set up.
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 ABS construction is usually framed as decent and better than cheap-feeling plastic, but not truly premium.
Media controls are functional rather than premium. The keyboard offers shortcut-based media control, but several reviewers miss dedicated buttons.
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.
Most reviews say the keyboard stays controlled and not overly loud, though one review mentions metallic ping from some keys.
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 mentions per key RGB underglow.
One review explicitly cites a 1ms report rate as part of the G512's update set, supporting strong polling-rate performance.

Portability is weak. Reviews repeatedly note that the keyboard is heavy, which helps desk stability but makes it less portable.
One review explicitly calls the board lightweight and portable.
The keyboard supports game-specific or software-managed profiles, and reviews also mention saved profile handling.
One review highlights preset sharing and downloading other users’ configurations.

RGB customization is one of the G512's biggest strengths. Reviews mention presets, custom effects, per-game lighting behavior, and broad software control.
Multiple reviews say the software lets users change colors, effects, brightness, and related lighting behavior with little fuss.
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 is mostly described as vibrant, bright, or attractive without being overpowering, though one review says the side underglow is weak.
The G512 is consistently described as a full-size, standard-layout keyboard. Some reviews like the compact deck for a full-size board, while others still see the numpad layout as bulky.
Several reviews praise the board for staying compact while still fitting a numpad.
Software impressions are mostly positive for customization and usability, but not universally so. Some reviewers found vague icons, complexity, or buggy behavior in Logitech's software.
The companion software is repeatedly described as easy to use and good enough for common remaps, macros, and lighting changes.
Multiple reviews credit the multilayer dampening and gasket construction for reducing vibration, hollowness, and harshness.
The only direct stabilizer review calls them decent, though larger keys can still rattle a bit.
Stabilizers are mostly praised for keeping larger keys controlled, though a few reviewers mention looseness or a need for extra tuning.
Switch feel is a strong point overall. Reviewers liked the clicky GX Blue and other switch choices, though some switch variants were called scratchy or mushy, so feel depends heavily on the version.
Reviews generally describe the stock switches as smooth, light, pre-lubed, and pleasant to use, though one reviewer calls the Wisterias fairly generic.
Multiple reviews highlight three switch choices: Romer-G Tactile, Romer-G Linear, and GX Blue. That gives buyers meaningful options for clicky, tactile, or smoother input.
