My fault I didn't notice in the description that these aren't genuine Miele bags. They are alright. Every time I vacuum, I have to open the vacuum, move the bag and snap the red part into place. An annoying popping sound can often be heard coming from the inner red round "door" that normally closes the vacuum bag itself. My personal opinion, my minimal saving on this product is not worth it. Sorry, but next time I'll definitely read better and get a real Miele.
