Field notes

The homepage organizes the work into separate checks for displays, keyboards, mice, webcams, microphones, speakers, refresh rates, and touchscreens, plus a six-step combined inspection. Its supporting material is unusually practical: the visible guide list addresses dead versus stuck pixels, four keyboard symptom categories, battery-life measurement, device resets before resale, and recording defects for a seller. The page labels its progress display as an example rather than a live result.
