Conflicts

A retailer power specification conflicts with the exact-model manufacturer specification for NS-TSC10A.
Direct-store and retailer stock observations differ by seller for the two Zojirushi products.
Capacity labels use cooked cups, uncooked rice cups, and vessel quarts across the frontier.

Unresolved and limited

The product frontier is non-exhaustive and is not a ranking.
No independent same-rice performance, reliability, or expected-life comparison was collected.
The exact Cuckoo manual and current authorized Instant Pot Duo inventory remain unresolved.
listing observations require purchase-time verification and human editorial review is still required.
