OP here.
DD got me a basic model for Christmas - T-FaL, analog timer and temperature dial. The basket is round, about 9"/22.5cm diameter - says 4.2 L capacity, but to me area seems more important than total volume.
So far the only meat I have done is chicken thighs - and wow it is so much better than my convection oven. Faster, better crisping for the skin. The chicken fat just collects in the bottom (no browning) and I am saving it, along with the leftover bones, for stock. The basket and trivet are non-stick and so far it is a breeze to clean. It also does a great job of reheating leftover chicken. For the second batch of chicken thighs I took most out early and froze them so I can grab one and it will take 8 minutes for an easy dinner.
I also did frozen french fries - they were better in the air fryer than in the oven, but I find frozen fries just adequate at their best. I want to try home-made fries and sweet potato fries. Really, the fries I love are the big fat greasy soft ones I grew up with in Quebec, not these super crisp things. Could someone please open a branch of La Belle Province or Dunn's here so I can get my fix of Montreal smoked meat and fries?
It doesn't take up a huge amount of counter space. I moved the toaster to storage to make the space.
I knew they are not real fryers, and since I never deep fry things at home I am fine with that. It is so much better than the oven. I am gluten-free and rarely make toast or toasted things so didn't need the toaster oven style, and there is a pizza pan insert for it that would let me do rolls etc if I want to.
So, definitely happy with it.
