It comes with big batch and small batch bowls and lids. The small one is perfect for cooking a single chicken breast. If I am cooking a couple burgers the big one has worked great.
All of the parts are super easy to clean and the heating element has just needed wiped down so far (cooking steak or bacon may require more). I dont have a dishwasher but all parts except the heating lid are dishwasher safe.
Even though there are multiple pieces (3 bowls/lids plus the heating element lid) they store easily as long as you have the space. They are not too heavy or bulky. I like that its glass so its easy to keep an eye on your food.
I have found it pretty easy to use. The instructions are helpful. Everything I have made has turned out well (as long as you pay attention to the times and type of food).
I've not made anything super complicated yet mainly frozen burgers, chicken bites, and chicken breast.
Another bonus is the air fryer does not warm the house up like the oven does. That makes it great for the summer months when its hot out.
This has turned out to be a great tool addition to my kitchen arsenal. I am still trying new things but so far it has been great!
