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.
Agreed with this. Big enough to cook multiple trays at once, and flips out of the way when done if you store it on the counter. Only downside is that it takes a little longer to cook than a traditional air fryer, but that’s a minor point. [Here’s](https://www.costco.com/p/-/ninja-flip-10-in-1-toaster-oven-air-fryer-with-added-broil-rack/4000359830?COSTID=iosapp_25.12.2&TRACKING=NO&sh=true&nf=true) a link to the model at Costco, since I don’t see it posted here.
This thing is the best.
Get the ninja one that is both. Done. Happy.
I have one of these. Fantastic air fryer, 9/10. Two key points: A: It cooks a little slower than many other models - if instructions say cook for 10 min at 350, it will be 12-13. B: The "flip" thing is really a gimmick, at least for me. It doesn't save very much counter space at all, so it just stays in the regular position. The trays / pans / etc can sit on top because the heat from the machine wont hurt them. Overall, however, an excellent buy at full price, even better discounted, and if getting it from CostCo, there is a great return policy if for some reason it breaks.
I like the flip part of it myself. I don't use it every day, maybe 1 to 3 times a week. I use it as a toaster, air fryer, and a mini oven. I don't have enough countertop space for all these items separately. It replaced a much older mini convection oven that I had for like 10+ years. It is a compromise appliance.
I've owned the Ninja Flip for like 5 years, and I love it. Technically the traditional air fryer version (with the basket) works better for "frying." But I also wanted a mini oven, and I don't have tons of countertop space. Convection oven works well too. I often use it cook salmon, chicken, veggies, etc If you use this a few times a week, the flip part works very well in freeing up space. I also use this for toasting bread because I didn't want a separate toaster.
Get the flip up Ninja toaster oven that doubles as an air fryer, and that conveniently flips up to increase counter space! Best thing ever. https://www.costco.com/p/-/ninja-flip-10-in-1-toaster-oven-air-fryer-with-added-broil-rack/4000359830
They sell this exact model other places as well. Found it at Costco, returned it and bought it from Woot for 40 bucks less. Its a great machine, no regrets. Ninja 10-in-1 Digital Air Fry XL Oven https://home.woot.com/offers/ninja-10-in-1-digital-air-fry-xl-oven-3?utm_medium=share&utm_source=app
