Scored on 78 merchant reviews we hold for Cart Lock:Block Checkout Rules, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 78 reviews we hold, with 12-month windows measured to 2026-08. 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.
