| 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 sensible wireless TKL on paper. Maker specs and a comparison listing are all the evidence. |
