I have a very similar range with the air fryer but not wifi. Never used the fryer feature. Barely used the oven....mostly recently when I started baking bread.
Seems like the mess it would make "frying" in the oven, it makes way more sense to contain that to a counter top fryer.
And wifi on an oven is ****ing ******ed. Especially if you can't use a main feature without it. I can't wait until ~10 years down the road when manufacturers decide to stop supporting the apps or backend services that run these things and people are stuck with bricked ovens, washers and refrigerators.

Kind of like how Belkin just decided to discontinue support for Wemo devices - completely shut down the app and cloud service that ran them. I only had a few outlets, and they're apparently still working locally, I just can't get in them to make any changes or connect them to a new network if anything ever changed with my wifi....but there are people that had their whole houses set up with their switches that are now basically useless. People are absolute pissed and I think some are pursuing a class action suite.
