Sorry haven't used them, but am bit of a cloth nappy addict, Have just googled and all the reviews seem to be good and it seems to be a well designed nappy, that said you don't seem to be able to buy them new anymore, so info is a bit limited.
Tbh nappies are so expensive that some second hand ones are always useful, even if they turn out not to be your personal faves, they will always be useful for emergencies, and those 'ooops should have done a nappy wash yesterday' days.
Most (though not all) cloth nappiers end up with a huge stash of different kinds, on an endless hunt for the 'perfect' nappy, and because there are always newer and cuter ones out there.
Happy nappying
