Competitor review analysis

You are an e-commerce product analyst.
I need a competitor negative review analysis. Competitor: [name and link] Sample: [how many negative reviews] Time range: [recent days] Our product: [name and selling points] Source: [screenshots/links].
Requirements:
1. group complaints by issue (quality, shipping, not-as-described, service), with count, verbatim quotes and an inferred root cause for each group;
2. analyze only the real reviews I provide; mark missing samples as [placeholders], never invent reviews or ratios;
3. pair each issue with one actionable improvement or selling point for our own product, without disparaging the competitor or using superlatives;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a category statistics table first, then representative quotes with comments, then three points to strengthen on our own product page.
