@jacel They have been a massive help for me in times of low spoons; throw in something, let it run, give it a quick shake halfway through, done.

Combined with a contact grill (almost impossible to burn stuff on that!) it's how I cooked for myself for quite a long time, and how I managed to eat vaguely healthy meals even when I didn't have energy for cooking.

I had very good experiences with a specific model sold by Lidl (no longer available); it had fins on the side of the round basket, which seemed to help a lot in getting an even crust on food, and made especially fries extremely well.

The one I have now isn't quite as good, but still definitely serviceable. Less crunchy results, though, and less evenly so. Also Lidl, different model.
