My experience with Fagor has been very good for obtaining replacement/repair parts

They list 4 or five different multi cookers, so check the size and label.
I got an instant pot and have been using it 10x more than my old slow cooker, probably 5x more than my slow cooker and pressure cooker combined. Trendy or no, it has helped me do more cooking for my family and less eating out.
