The quality and build of the accessory and its fitness to use in air frying, especially around the high heat of fryers. A lovely deep ridged inner helps grip hot trays and handles without fear of slipping. Our only grouch with the mitts is they are pretty small, which is OK for small to medium hands, but large hands would be unlikely to be able to use them.

The sustainability of the accessory is reusable, of a quality to be used repeatably, and fit for purpose. We tested the liner with a batch of fat chips sprayed with a bit of oil. With the liner, the chips took a couple of minutes longer than without, but the result was the same for both, with golden, crisp chips with a deliciously soft middle.The casing is covered in soft silicone to seal and prevent food lodging in the crevices. In addition, it is washable with antimicrobial technology to reduce bacterial growth, making it super safe to use.
