I really wish I had bought an air fryer sooner, they cook food much faster and don’t use oil.  
As much As  i  know there have 14 types of Air fryer . 
Oh wow I didn’t know they even had that many types of air fryer. Surely they all do the same thing no. 
as customer  review i  know  the  Ninja AF 100 is best  
Yeah I really want a Ninja one, however they are just expensive and I haven’t used an air fryer before, next time I need one I will go for ninja. 
I also think so it is a good choice . 
In an air fryer you can pretty much make anything, from fries to steak to a whole chicken, pretty amazing to have in the home. 
It  is also capable to 1 kg beef at a time 
Oh wow, I must try make something with minced beef next time I use it.
you can check out  slow cook Beef which  would  be your  main dish  and beef steak with mushroom is another  choice can be
