| Research take , different | The most complete mechanical 75% in the Q line: reviewers praised the build, the sound and the 2.4 GHz option. The tall caps and fixed slope are the recurring complaints, so a wrist rest is worth budgeting for. | A wireless Hall-effect full-size on maker specs. Evidence for this exact model is Keychron's page; the only review found covers the wired J2 HE 8K sibling, so how this board feels is not independently documented. |
