I am excited about this film. I use it now are about 5 months in our Angel Care. The refill Although initially a bit fiddly but once you get the hang of it works quite well. I've followed the instructions supplied with the top up, the first time. That was me but eventually too awkward. So I simply cut 2m foil and stuffed in the not cut tape. Actually, one should separate the upper ring of the cassette, fill the sheet and then set up the severed ring and stick firmly back with tape. However, my tape has solved after some time, remained stuck to the film and has given me so purely holes torn ... I can not now claim that more odors come through this film than in the original. Sure, you can not expect that no odors coming through. But that is not the case in the original cassettes. The diapers are after all not hermetically enclosed in the bucket. But the odor is actually reduced to a minimum. Even in the summer at higher temperatures can smell no more than at normal room temperature. Besides unless one makes the bucket directly into the sun or next to the heater. But that should indeed be clear to everyone. I, the film wants to save some money each recommend the and do not mind a bit of time to invest into the refill.
