Good product, acquire knowingly

Miele bags are top quality: 10/10: robust, very permeable, practical and well thought out (rattles closing the bag).
These bags are medium range: 6/10: If the bag is sturdy, the cardboard attachment system is more fragile, I think the filter bag a little less than Miele (top notch), and n 'there is no valve closing the bag. So we end up breathing the dust when you leave the bag.

I do not want to waste my Miele top quality bags for my work (rubble), preferring to keep them for finishing. Not sure I use for my daily housekeeping (for troubleshooting, they are very good).

Conclusion: Good product for those who want to optimize their cleaning costs.
