Strangely, for me was the closure of the original cardboard and this one is from - blue - plastic. In addition, the bags are larger than the original bag for Miele S4 Ecoline. However, you fit into it, as long as they are empty. I "practice" now with the getting used to bag whether, when it is full and I will not be announced in advance, any catastrophe happens. Postive is in any event that spare parts country has given me an extended return opportunity for unopened bags, if there are difficulties. Very good customer service, I think.
As it turns out, everything went fine. The bag can be easily removed to distribute without a portion of its contents in the area. These bags are therefore also suitable for Miele S4 Ecoline. (Result July 2012)
