First, on the subject of replenishment. With a little practice and taking into account the tips previous testers, refilling does not fall very hard. You do not get quite as much film in the cassette as in the original, but to get along just fine. But ... I did not think you would notice so much the difference. With the original film you can even keep the stinky diapers relatively well in the apartment. With the Nachfüllfolien it stinks quite badly, so that the bucket has now evicted onto the balcony. For the first breastfeeding baby diapers that goes with security, but real bad diapers are really for Nachfüllfolie too much.
