What is worth knowing.

Headlines first. Open evidence only when you want the source trail.

CheckedCan you trust the review pattern?

Reviews rose from 100 to 231 between July 30, 2025 and August 12, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 100 to 231 between July 30, 2025 and August 12, 2026. The largest rise inside any single 30-day window was about 23, so the count moved in steps rather than in one burst.
