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. This compares products grouped by one sub-score inside a single type; it flags where that sub-score is not informative, not proof that the score is wrong overall.
