Instant Pot's Duo Crisp 6.6qt two-in-one pressure cooker and air fryer is truly an amazing piece of equipment.  Where some other combo units have two lids, Duo Crisp integrates the "Ultimate Lid" to perform all tasks without the need to store and change out parts.  The 6.5qt capacity gets used up rather quickly if you're air frying, but that's no reason to shy away from this ingenious device.
