With the papers that came with it you can make 500ml easy as the papers went right to the top but the filtropa's are a bit below the top and also a little narrower so some coffee can get behind the paper if you're not careful. I probably wouldn't be bothered by it if I hadn't used the other papers first.
Ah yeah that's fair. I watched a couple of reviews before I bought one so I was prepared for the fact 450ml was about the limit, but if I'd started making 500s then had to go down to 450 I think I'd be annoyed too.
