Overall score includes:

Performance (70%): Weighted equally on crumbed chicken breast nuggets, thick-cut frozen chips and home-made french fries. We also test new models on chicken wings and roast pork. These tests weren’t conducted on previously tested models so don’t contribute to our performance or overall scores.

Ease of use (30%): Assesses how easy it is to assemble, clean and store the cooker and use its controls.

Running costs calculated on 30 minutes’ use 3 times a week (electricity costs of 26¢/kWh).
