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

Legend visibility is mixed: some reviews call the legends clear, while another found the dark bottom-row type hard to see.

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

Macro customization is well supported through software, function-layer controls, VIA remapping, and anti-accidental-trigger settings.

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

Materials are plastic but generally acceptable for the price, with reviewers saying the case does not feel cheap despite rigidity limits.

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

Media controls are not a standout native feature: one review notes no knob, while another remaps keys for volume through VIA.

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

Noise level is strongly context-dependent, ranging from quiet and subdued to noisy or hollow depending on reviewer and key pressure.
