Just to be clear for those contemplating this, the air-fryer is a separate accessory that can be purchased for the Instant Pot, though they are now making an Instant Pot package that includes the accessory.

The Instant Pot itself lets you cook a combination of things that you would ordinarily need a pressure cooker + slow cooker + yogurt maker + sous vide + etc., etc. all in one appliance.

It's not magic. If you like cooking and like trying new methods it will be good for you. If you hate cooking or prefer frozen crap out of a box, this unit will not help you.
