Due to the many positive reviews I have resorted to these bags, but they probably share the fate as any other third party bag. They do not fit exactly. An original bag I put a simple, doing the cover and you're off. In this bag I have then always check whether the intake manifold also really rests exactly, otherwise I may sweep after the vacuum cleaner interior, which is probably not the longevity of a vacuum cleaner benefits. I will no longer buy these bags.
