Review on Crucial Vacuum Replacement Vacuum Bags Part # 780510000010 - Miele FJM Bags Compatible with S246, S256, S300, S700, S4000, S6000 Models - 5 Pack Bulk for Home and Office by Jennifer Johnson

Before I bought them I noticed reviews from many other brands complained about cardboard collars instead of plastic collars like Miele branded bags. I am pleased to report that they have plastic sleeves and fit my vacuum perfectly as advertised. I've already gone through 4 bags so I figured it's time to reorder. I've noticed that some of the more recent reviews have complained about cardboard and poor fitting for *these* bags. I will say that Crucial Vacuum sent me the wrong bags on my first order, but when I called them they fixed it right away. The label on the package indicated that I had received the wrong packages. When the correct bags arrived they had red plastic collars as in the picture. I can only hope that this confusion explains the bad reviews because these bags fit me perfectly, they seem to be of high quality, they are definitely better than the overpriced Miele bags and I will *repurchase* them. An order. I will update the review if anything has changed. Update: I ended up stocking up by ordering a pack of 25 of these bags (to get the best price) and the bags have plastic collars and fit exactly as advertised.
