We got a Breville at home recently and I couldn't understand what the hype was all about, it did exactly what my last countertop oven did even in Airfryer mode.... this is making sense now. We were already heavy users of the old convection only model, so this didn't seem like much of an upgrade. I think the marketing hype is just pushing people to realize a countertop oven of any sort is very useful. (That said, the Breville is very well made and we'll keep it around. It works well, just didn't quite taste much of a difference from what we had before - an older Cuisinart FWIW).
Be sure to use the basket and don’t overfill it. But yeah - I don’t have an air fryer but if I put some frozen French fries or the like in there the air fryer instructions absolutely do not get the food done.
