Layout support is solid, with evidence for Q3-specific 80% design and related variants using different layouts.

Legend visibility was mixed: shine-through legends were often praised, but some reviews noted uneven lighting, hard-to-read unlit legends, or localized legend issues.

Legend visibility has direct positive support, with the review noting easy-to-see legends.

Macro customization was one of the most supported strengths, with reviewers repeatedly citing KEYCONTROL, G-Shift, profiles, and up to 15 functions per key.

Macro customization is broad and useful, though one review notes manual mouse-click insertion as a limitation.

Materials quality was usually viewed as good for plastic, with reviewers describing sturdy, thick, or high-quality plastic while noting it is not as luxurious as metal.

Materials quality is high overall, though the ceramic model evidence introduces a durability tradeoff not tied to the aluminum Q3 HE.

Media controls were a recurring weakness because most reviewers missed dedicated media keys and instead had to use function-layer controls.

Media controls are good, with remappable media functions and a knob called out.

Noise level was consistently praised, with reviewers calling the board quiet, soft, pleasant, muted, or office-friendly.

Noise level is mixed: some reviews praise soft or premium sound, while one flags loud typing.

Onboard memory received positive evidence where mentioned, letting users store lighting, profiles, or settings on the keyboard.
