Scored on 10 merchant reviews we hold for RN: PreOrder & Back in Stock, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.

Computed from the 10 reviews we hold, with 12-month windows measured to 2026-09. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.
