What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
CheckedCan you trust the review pattern?
Reviews rose from 7 to 17 between September 30, 2025 and May 12, 2026 — no sudden jump.

Written reviews rose from 7 to 17 between September 30, 2025 and May 12, 2026. The largest rise inside any single 30-day window was about 4, so the count moved in steps rather than in one burst.
