ShipFlux vs NimbusPost
Weight Freeze that actually freezes.
NimbusPost competes on cheap entry rates and its “Weight Freeze” feature — which proves the feature matters. But it carries the same billing-dispute complaints (1.4/5 Trustpilot). The feature is right; the execution and the SLA behind it are what fail.
