Dual zones excel, but bulky with small baskets.

Honestly I returned it. I felt like it didn't do anything well. The basket for the air fryer is also really high up and didn't work for some stuff and burnt it or it didn't fit. I ended up returning it and getting the corosi toaster oven and I like it better so far.https://www.costco.com/p/-/cosori-30-liter-smart-air-fryer-toaster-oven/4000415415?adobe_mc=TS%253D1765369219%257CMCMID%253D73997581491133952237276407342534395761%257CMCORGID%253D97B21CFE5329614E0A490D45@AdobeOrg&mboxSession=f4f06bc4-9ab7-4d58-8641-bf2e9026e3c5&sh=true&nf=true
I returned the ninja flip and got the cosori toaster oven. It does everything the flip does and it's bigger. A traditional basket air fryer is probably best for only air frying, but I wanted the other options as well. https://www.costco.com/p/-/cosori-30-liter-smart-air-fryer-toaster-oven/4000415415?adobe_mc=TS%253D1767411720%257CMCMID%253D73997581491133952237276407342534395761%257CMCORGID%253D97B21CFE5329614E0A490D45@AdobeOrg&mboxSession=5091034b-e479-47e9-a624-a1fdcb423789&sh=true&nf=true
I have a small counter too. I bought a Cosori multi function toaster oven. It's 17W x 16H x 16 deep. It Air fries, toasts, broils, dehydrates, bakes, defrosts, roasts, slow cooks and ferments. It also has a pizza setting. Simple to use! Comes with a basket a boiler pan, and a regular rack. I bought this instead of a microwave and I didn't have space for a toaster either, this does it all and only cost $185. when I moved in. I absolutely love this thing and get way more use out of it than a microwave.
I have a Cosori toaster oven style air fryer (some of my kids are all bougie and have Breville and the other a Ninja). All are terrific because they can all make a frozen pizza to perfection. Yes, longer pre-heat compared to a basket...by maybe a minute. My kid with the Ninja XL can make a full dinner with sides all at once for her and her husband, so that versatility is off the charts. I find with the mesh basket tray on my Cosori that I don't have to flip foods and they're much easier to space out to allow the circulation that is the science behind why an air fryer works.
