Insta-pot came up with a special lid that converts the pot into an air fryer. Said lid cost almost as much as the pot itself. Insta-pots are too small to really work as an air fryer, so we no longer use the lid. Instead we bought a dedicated Insta-pot air fryer because we trusted the quality of the name.
So, they are branching out somewhat, it’s just going slow because it is hard to do perfection twice.
