Question about Philips Airfryer HD9270/96

This one has no WIFI connection and cannot be controlled through the NutriU app. Otherwise they seem to be the same.

I don't know, but I can well imagine that you pay for a lot of superfluous bells and whistles with the more expensive device. The appliance I bought more than meets all my needs.
By the way, my fridge, my shower and my bedside rug don't have WIFI or an app either and, perhaps for that very reason, they always work just fine!

The HD9270/96 does not have a Swiss plug.

I don't know what the difference is.
I have tried to make fish, vegetables, meat, chicken, bread, maffin, in short, different things and I get on very well.
