I have used the dehydrator function, and it works very well, but takes the gizmo out of action for understandably long periods. I wanted a chamber, with shelves, as opposed to stacked trays. It also means, when in air fryer mode, we also have multi-shelves/layers.
I've yet to use the rotisserie, despite multiple promises to myself.
MrB is the world's cynic when it comes to multi-purpose gadgets, but he agrees this one (along with the IP and combi-oven) works.
