Is the Ninja Combi 12-in-1 Multi-Cooker, Oven & Air Fryer worth it?
Yes — if you'd use it instead of the oven.
It's shaped like a mini oven with a side-opening door. Its combi modes add steam while it bakes or air fries, so pasta, rice or grains cook in the deep pan below while chicken, fish or vegetables crisp on the tray above, usually in under 20 minutes. It also air fries very well, bakes with crisp golden tops, toasts, proves dough and slow cooks, and the steam function helps clean the inside. It's easy to set from the front panel, and the non-stick pans clean easily. Learning the combi timings takes some trial and error, the pan is too small for a big family, it only air fries on one level, it gives off a lot of steam and there's no pressure cooking.

What owners say
Owners love how easy it is, how quickly it cooks and how easily it cleans, and many use it instead of the oven. The main complaints are that it's smaller inside than they expected and confusing to learn.
Good to know
- The inside is smaller than many owners expected: it suits two to four people.
- The many modes and the thin manual confuse some owners.
- A few units stopped working, or arrived damaged.
- Air frying uses only the top tray, so you can't air fry on two levels.
- It lets out a lot of steam, and the condensation tray needs emptying.

How we reached this verdict
TechRadar found its combi meals crispy yet tender and its air frying excellent, but the modes confusing and the timings tricky at first. Ideal Home calls it hugely versatile: combi meals cooked in under 20 minutes and its bakes beat a real oven, though it steams a lot and can't air fry on two levels. Verified buyers at Costco in the US (US version) mostly love how easy it is, how quickly it cooks and how easily it cleans; the main complaints are that it's smaller inside than expected and confusing to learn.
