My experience was that it was shit.
We actually got it as a housewarming gift, which was (and still remains) a lovely generous gesture but I hated it and was not displeased at all when it broke after a few months of very very minimal sporadic use (me going back to it thinking it must be me that's the issue and trying again)
They're huge and look awful on the countertop, storage of it is a pain as is cleaning.
All that aside the results are just so average. It's called an 'air-fryer' because in theory it replicates deep frying without oil. In actuality it is a counter top convection oven. You do need to use some oil for anything approaching a decent result as well as need to turn things consistently and I found pretty much everything we cooked in it depressing, with a dry texture, inconsistently cooked with a sort of strange aftertaste - you know when things just taste of the oven.
The chips were passable (albeit absolutely not comparable to deep fried) but realistically I am not having chips on a weekly basis at home, so would rather just get some proper ones when I do and not suffer the air fryer edition.
Each to their own though, I bought a slow cooker instead and think that's great and I know not everyone likes them.
