We have this model. Can confirm it cooks unevenly. You can counteract it if you’re mindful to turn the food through the cooking process, but it can be a pain

It's not the best. Definite differences in heat levels between the front and back of the drawers so you have to move things round more than you ah pull. Zero preheat time though and it's got a small footprint for so much capacity.

This model of ninja is inherently flawed as an airfyer and the heating element is at the back. Reviews show it can lead to uneven cooking. If you have the space opt for the side-by-side ninja dual basket one, it goes up to 240C as well.

Go with the Ninja. Ninja makes consistently good quality that lasts years

Same. I have this model and cannot think of a single criticism of it.

I’ve had no problems with it. You go have to shake the basket or rotate larger items but that’s true of air fryers in general.

I’m usually not an ‘on trend brand’ person but… I have a lot of Ninja ‘never stick pans’ - and they don’t. A Dual Stack Airfryer - it’s great! Easy to clean too. A Ninja multi blender/processor - so much better than anything similar I’ve owned before. I recommend Ninja, yes, there’s hype, but in my experience they do live up to it!

Try this double stack air fryer by ninja. Looks very cool, takes less space. Plus it has some functions which genuinely surprised me - like you can cook four different kinds of food at one go

Ninja double stack has been a cool addition to my kitchen. The sync function is super cool and it fits right into my tiny Mumbai kitchen

I have that Ninja model and I find it great. It is very easy to clean and is simple to use. Great to be able to cook two different things at once with different times and temps and have them done at the same time. (Sneaky edit for typos)
