I may be completely wrong, but to me it it sounds like (after watching the link you posted) that the Cuisinart oven is not really the same as the other "air fryers".
I have a Breville toaster oven which seems to have the exact features as the Cuisinart, including the convection feature.**
It is pretty much just like my convection oven in my range, only smaller.
**The cuisinart does say it has a "high speed fan", so maybe I'm wrong.
It is great for cooking a small batch of something when I don't want to heat up the range oven, but I just don't get the same result as using my dedicated "air fryer"
It is pretty much just baking or broiling, even when you use the convection feature.
Looks like a nice appliance, I'm just not sure it will give the same result as a dedicated airfryer.
