Our expert product tester Helen had a mixed bag when reviewing this buy. Whilst she overall liked the idea of the deisng, having to cook at the same temperature on both sides, combined with the frustrations she experienced with the perforated dividers, left her thinking you might be better off opting for an air fryer without the flexible zones. And instead plumping for either a decent size single zone or a good dual zone air fryer.

Some of the more common pre-set programs are: air fry, slow cook, steam, sauté, grill, bake and roast. Other functions such as keep warm or reheat are useful, too. Like the Ninja, this air fryer has five other functions, and all of them are perfect for everyday cooking. The bake function is ideal for bread, the reheat function works for leftovers and you can even dehydrate oranges inside with the ability to set the temperature low for a long period of time (up to 12 hours).Two baskets allow simultaneous preparation of two foods with different cooking requirements. Prepare fries in one tray, and vegetables or meat in the other, with both ready to serve at the same time. You can mix and set the cooking programs with different times and temperatures, which are ready at the same set time thanks to the SYNC function. If you’ve settled on buying an air fryer from Ninja but would like to take a more in-depth look at the range, be sure to take a look at our best Ninja air fryer roundup. The sync and match cook functions allow both compartments to be ready at the same time with a temperature pause and resume function The main reason to buy this air fryer from Russell Hobbs is the flexibility that comes with being able to split the basket into two zones, much like the Ninja FlexDrawer, which we've rated above.

Dual zone air fryers do everything your usual air fryer can do, times two.So you can cook with the same time and temperatures across both drawers (effectively doubling the capacity of a single drawer use) or you can control either drawer independently.

How we tested the best dual zone air fryersAlongside a varied set of preset functions, the Genius XL’s standout feature is its rotating paddle, which does away with the need to pause your cook and shake midway through, instead gently stirring your food throughout for consistent results. The air fryer’s 1.7kg capacity is split between two cooking compartments, with the bottom compartment utilising the stirring paddle and a second static section sitting on top – though the latter can be removed for extra room if needs be.
