■ The catch — co-equal billing, always
The pot is a wear item. A ceramic coating scratches and the inner pot eventually has to be replaced, where the stainless pots in the Instant Pot Pro and Duo Plus are effectively permanent — and a replacement pot costs far more than the $7 sealing-ring two-pack you will buy every 12-18 months regardless.
Dealbreaker? The Instant Pot Rio is $30 more with genuine parts supply ↓

Traps — this verdict avoids
Why the Cosori 6-Qt 9-in-1 is right for you
It avoids every trap below — and for just me, under $80, it is the pick because it delivers:
Phantom quarts
The number on the box is total pot volume, not cooking capacity. A 6-quart cooker pressure-cooks about 4 quarts — the 2/3 max-fill line — and about 3 quarts of anything that foams, like beans, rice or pasta. Size up one tier if you batch-cook.
The 10-minute lie
Electric cookers hold 11-12 psi, not the 15 psi of a stovetop cooker, and need 7-15 minutes just to come to pressure. A recipe billed at 10 minutes is realistically 25-30 minutes from plug-in to plate.
The model number is the product
Rio, Duo Plus, Duo Crisp, Pro, Pro Plus, Pro Max and Chef Series photograph almost identically but differ in inner-pot material, functions and price — and the Pro Max is currently unavailable on Amazon while the Pro Plus is not. Match the model number, never the picture.
