I've uses my mooncup UK the past week and it's great !!!
no problem with getting it in properly
i could hold it in the hole day (but i know that has to do with how much blood you lose)
only with getting it out (and breaking the vacium) i need some practice, but so far, for my first week, i don't want to live without my mooncup anymore !
I found a Dutch site : menstruatiecup
about all the differend cups, how to use, and all the further information...
