Handling I personally found quite easily. Cut required length, little slide underneath and fill the film in the cassette. Trouble System.
Drawback so far: Either through the harder plastic (rather feels like a sandwich bag; the original foil is thinner and more flexible) or by the lack of anti-bacterial coating, it smells rather quickly and strongly to the old Pampers.
That actually flunked me. I buy the bags Y Bonus, so that it no longer smells.
But as long as you can use the bucket with the bag and are not need to trash for each Pampers. Otherwise, you can put him out of the nursery at night yes. But the whole point is not that.
So rather Rating 2-3, saving money YES, rather no odor stop.
