I'm going to argue the above largely misses the point of what makes a good air fryer and what you have linked about is actually just a fancy toaster oven.

You did mention it yourself - "It gets a little dirty inside".

Compare it to the $30 air fryers that are essentially an insulated cooking pot with a detachable heating element. They do the same thing but are so trivial to clean since they are a cooking pot that fits in the sink.

It's one of those things in life where cheaper is better in my opinion and i do not recommend the above product at all.
