undoubtedly saves money here compared to the expensive original bags, but that beats itself felt on the quality down. The plastic inserts are clearly puny and thin (loose stop) and the locking of the full bag is simply insufficient. The original here has a well-fitting lid, which closes on hygienic train. This bag has a not really snap red Umklappdeckel made of thin plastic, which is anything but seals. The bag itself acts even thinner than the original in its wall thickness. I suspect that after a few bags of this type so some stick to the dirt on the motor protection filter and will be in the bag compartment of the vacuum cleaner.
