Limitations

Review-derived and observational: rates are the share of sampled reviews that mention a problem, not a lab-measured failure rate. Reviews are self-selected, the corpus is a 2023 vintage, and problem mentions come from keyword/NLP labelling. Association is not causation. The delta compares each product's first two review years with its last two (>= 4 distinct years and >= 4 reviews per side); it measures how visible satisfaction drifts, not a physical failure time.
