I tested it with Schirmer organic coffee. A "large cup" does not work out really with them, the coffee is too thin for the simple shovel method. But it is also very clear here that this is espresso capsules.
I just fill therefore two capsules without much consolidation ritual and then press stop twice the small cup. The mini effort more worthwhile. I have great coffee (with crema on top) and no crumbs in the beverage.
Oh for cleaning I can only recommend the Easy Learning cutlery (plastic) of Nuk. The children spoon fits perfectly into the capsule)
