What reviewers say
Reviewers praise its looks, pleasant typing feel and sound, the depth of its magnetic-switch gaming features and the easy web software, and call it good value. All three regret that only Keychron's own magnetic switches fit; Tom's Guide found the 96% layout awkward, Notebookcheck found the tray-mount design stiff, and Windows Central found the supplied cable too short for the wired-only software.
