This was my third bag order and how it differs from the first: The first order came in a black and white box; everything worked perfectly and I could not tell any difference in the Miele's performance (noise level/vacuum cleaner performance). Second, the noise level has increased significantly for a relatively quiet machine. Thinking maybe some manufacturing defect, I ordered a third time: not only is the noise level as bad as before, but the width of the board has also decreased and slips out of the bracket easily. Reorder this brand? In fact, one would have to prioritize price over functionality.
