This is the first potato ricer I have had. It is large, you could easily mash one potato at a time in this. My only gripe is that whilst it's great it comes with different attachments, not sure why you would need to change them but then I am not a professional, the attachments are not secure so when you lift the handle to put more potato in, the attachment comes with it, a little flick with a knife and it falls back into place. Reading other reviews apparently this is worth the little hassle as opposed to having a smaller ricer. I am happy with it anyway!
