I have the same one as Ruf -its great fits all sorts of stuff even now that she only has one bottle a day but I do her sippy cups etc....

Just keep in mind with dummies that they shouldn't be microwave sterilised as the heat goes too high for them and can cause the rubber to wear out quicker than it should which is dangerous. I found that a a hot kettle boiled and then poured over them in a bowl was fine to sterilise.
