I bought this vacuum cleaner bag for my Vorwerk, because my original Vorwerk bag appeared too expensive. I had to regret about 1 year later bitterly, as the performance of my goblin subsided and the Vorwerk service technician showed me that thanks to use of this filterless bag filter was added in such a way that he had already suffered irreparable damage. Here is saving at the wrong end !!! And who should be these "leading third-party" or these bags are supposed to be quality checked by whom, is questionable. I will definitely not support such low-budget productions.
