The quality is the price absolutely reasonable. But who expected that he has for the competitive price gets the same quality as in the Swirl-bags did not understand the basics of economics. The bag reminded me at the beginning of handkerchiefs that have been glued together. Much thicker they are not. They also have all vent holes of about 1 mm diameter. Since not only a hair fit through. The suction power is easy underground. I vacuumed my bedroom and asked me why it then was just as dirty yesterday. Was a great Anschiss with my wife who had not believed me that I "really" sucked. Once I wanted to change the bag, I realized that this was not even really full, also was a lot of dirt and coarse dust before the filter of the vacuum cleaner motor. This was the third time that this has happened to me with the bags. Much of the dust was so easy just redistributed again. I could "suck" with a hairdryer.
I've let myself be blinded by the great recession and price. Will throw away the rest of the 17 prey and got me yesterday bought a pack of 8ter Swirl. Although there are more than three times more expensive, but they have HEPA filters and are strangely also 3 times as thick as this one. For me, a bag must absorb as much dirt as possible and not redistribute him. Who sets the price value should buy this booty, they are low indeed.
I was not satisfied with this product, two stars are there for the cheap price. Maybe the others have yes (AEG Vampyr my 2300) and good Motorvorfilter intercept the remaining dust and other vacuum cleaner.
