Once you know how it cooks, the spec sheet matters more.
What the seven cooking functions do
The 7-in-1 label covers pressure cook, slow cook, sauté, steam, rice, yogurt and keep warm. Program counts vary by generation: current US copy lists 13 customizable programs, while older Duo descriptions count 14. Check the controls on the specific unit you buy.
Size, controls, and included accessories
Nominal capacity is not dinner yield. Pressure cooking tops out at the 2/3 line, including food and liquid, which works out to roughly four quarts of food. Up to six servings is a capacity claim, and it depends on your ingredients and portions. A family of seven will usually need a second batch or a bigger pot.
Controls are button-driven, with adjustable time and pressure, automatic keep warm, remembered settings and delay start. Lid design differs between Duo generations: newer lids use a separate release switch, while older ones use a rotating handle, so follow the instructions that came with your unit. The stainless steel rack is included, but accessory bundles vary by version.
