Foodi Dual Zone Series
Dual zones for smart cooking, but baskets are small.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Yes we love our airfyer, Ninja Mini 2 QT. Tops out at like 800 W, heats very quickly, great for leftovers. Takes up almost no space
If you have the power, the ninja 2qt air fryer has become my fav appliance and its quite compact
Meh. Bought the Kitchen System and the skinny air fryer in the last couple of years and while they both do their jobs, they have annoying eccentricities. Probably won't buy Ninja again.
As someone who was skeptical, 100% yes. We use regularly for reheating, meats, veggies, etc. Space is definitely a concern, but we have a slim model from Ninja that we were able to carve out space for in our cabinet just below where we plug it in. Worth it because we use it so much.
I have the Ninja mega drawer and use it for baking. Get the bigger one though as the compact one isn’t deep enough (I had both).
I bought a Ninja pod based on recommendations from The New York Times Wirecutter. Was $89 at Best Buy.
