Yes, because an airfryer is set to a timer (which is super easy to use), the chances of putting something in then falling asleep is low (its there because you could say, put a piece of bread in and then set it to roast for an hour but that is highly unlikely, it's just now how they're used compared to an oven or grill).
I really was reluctant, I thought they were for doing slightly faster and somewhat substandard chips and as I only bother with chips if they're from the deep fat fryer, I couldn't see the point.
However they've come on a long way, and they're not a replacement or substitute for a deep fat fryer, that is a huge misconception.
They are a smaller, much more efficient convection oven, with some extra features, including easy to work and fairly intuitive pre-set programs and timer/heat settings.
It does take a bit of time to get your head round how to cook your usual things in them, but thats really the same with any major gadget change.
