Field notes
The homepage organizes the toolkit around common failure points rather than a single device category. Individual checks include audio-channel separation, approximate screen hertz, controller stick drift, mouse polling rate, and a five-try reaction test. A used-device pathway is described separately, with a 2–3 minute sequence covering core hardware and a shareable QR-coded report.
