Verdict: This stone/gold European DualZone is a finish-specific model, not DoubleStack. The French store mixes a 9.5-litre title with 7.6-litre/four-mode copy; use the matching manual and rating label rather than that contradictory summary.
Regional model: Ninja DZ400EUSTGD · EU. This is a European/UK model code. A US listing with a similar family name is a separate appliance; check the full code, plug, electrical label and local support.

Two drawers, one dinner deadline
The useful feature is separate settings and handling for each drawer. Synchronised finishing can hold one programme so both foods finish together; matching copies a setting across zones. Neither feature checks whether every item is cooked through. Count the space in each drawer, rather than adding the two capacities and imagining one large roasting pan.
Who should choose it, and who should compare another type?
This stone/gold European DualZone is a finish-specific model, not DoubleStack. The French store mixes a 9.5-litre title with 7.6-litre/four-mode copy; use the matching manual and rating label rather than that contradictory summary.
A main and side, mixed preferences or larger batches: check usable space per controlled zone. The linked comparison below explains the closest alternatives; we do not assign an invented cooking score or claim this model beats another in tests we have not performed.
The Spanish manufacturer listing identifies a 9.5-litre six-function model, while the French page mixes that title with smaller-model body copy. The inconsistency is a reason to check the supplied regional manual, not a reason to combine the two sets of specifications.
Cleaning, materials and long-term ownership
Check the cleaning instructions for each supplied vessel, rack, plate, probe and lid. Cool the removable parts before washing, use non-abrasive tools and keep the powered body out of water. A dishwasher-safe removable part does not make the heating unit or probe assembly dishwasher safe.
Coating and materials descriptions can change between components and production versions. We do not extend a current ceramic or PFAS-free statement to every historical Ninja appliance. For a used unit, inspect the cooking surfaces and use the exact model’s replacement-part list.
Questions before ordering
Can I use only one drawer?
Two-zone machines can be used for a smaller single-zone job following their own instructions. Check the exact loading and programme guidance; a two-zone total capacity is not available inside one drawer.
What should I confirm on the listing?
The full DZ400EUSTGD code, region and voltage, new or refurbished condition, supplied cooking parts, and the seller’s warranty and returns. Product photography and a familiar family name alone cannot establish electrical or spare-part compatibility.
