We have the Ninja Foodi 6.5 quart. it does insta pot, crock pot, air fryer, all in one. I think we've had it for 3-4 years and it works well. I for sure liked that it did multiple things, so we could have 1 appliance with two lids vs 3 separate ones.
We mostly do crockpot, some air frying for chicken nuggets and hard boiled eggs. We did try mac n cheese and that was really good. I'm not creative with food making so I just need to find more recipes using it for things.
