| Research take , different | A wireless full-size QMK board known only from specs and a comparison listing. | 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. |
