At first I was very enthusiastic about the price - performance ratio. The Passgenauhigkeit top of the vacuum cleaner. But then came the rude awakening that I had to unfortunately find that the goods at the price is totally unsuitable. DC 3 of the bags are lined up in a place formally in the nipple. Respectively, a side seam had come loose or is easily torn. Probably a manufacturing defect. My vacuum cleaner has survived it after I now had several times completely clean it. You can imagine that the entire interior was completely messed up. In future, I will prefer to buy to the amount again only 4 bags of a brand manufacturer, but will then stop and do not like to tear when you press the sucker. Mfg. I have also written to the Seller. Well, not all of Amazon's super !!
