very good fabric bags for vacuum cleaners Fakir

I have the past two years a Fakir vacuum cleaner and take only this bag, because I'm not sure if the other bags, which are specified for the Fakir vacuum cleaner, really fit, because they look completely different. I am very satisfied with the bags, although I find them expensive. They have a good quality, are very thick and so far I've never had the dirt in the vacuum cleaner inside, as it was the case with other vacuum cleaners and bags. Everything is tight and seals well against the pipe end of the vacuum cleaner. Therefore 5 of 5 stars.
