The "extra" "only" has a timer, time setting according to recipes. (was enough for me) The "genius" has 9 programmes and is therefore more convenient in terms of settings, and also switches off automatically. The "genius 2in1" also has a separate, attachable basket for additional, simultaneous food preparation.

I don't know exactly. I think you can get 1.2kg in. But then it takes a very long time until they are good.

I have been using Actifry Extra for a long time and it has never gone "bad" for me/us afterwards

We always make potato wedges. (wedges). Also from fresh potatoes. They're crispy. We haven't made chips in that sense yet.

Sure, 1-4 people, you can determine the quantity yourself

Well... unfortunately I haven't managed to produce any really nice ones yet...

Yes, it is important that you rinse the fries well beforehand so that there is not much starch in them. This makes them crispier

No, unfortunately it doesn't, but it's never had any problems so far. The "bigger" brother has the automatic switch-off. The appliance was too big for a 2-person household, so I switched to the smaller version, but with small compromises. Otherwise TOP appliance, dishes turn out very well!
