10 GN Bags Compatible with Miele Classic C1 - Complete C2 - Complete C3 - S2 - S5 - S8 - [S800 - S858] - [S600-S658] - [S400i - S456i] Canister Vacuum Cleaners. Includes 4 Filters 3D Technology.

Haven't used yet, but NB: These are clearly lesser quality. Seems to be a cheaper material (may work fine, but quality difference in material is obvious). More importantly, dimensions of Miele GN bag are different. Miele is 11" wide; the Casa Vacuum bag is 7" wide with side pleats fixed on top and bottom of bag that permit a (partial) extension to 10" (I say partial because the pleats, fixed at top and bottom, permit expansion only in middle of bag. The ends are fixed at 7", so a significantly smaller bag, presumably requiring more frequent changing. Amazon sells 8 Miele GN bags for $27; sells 10 Casa bags for $17. I'd say Miele is clearly more expensive, but, considering above, by less than the straight cost/bag calculation would suggest (assuming, of course, otherwise equal performance, which I've yet to confirm).

Great set of bags, fit Miele vacuum cleaner and much more cost effective. Second time buying these and happy with how they work.

Great product, great price! I regret having bought this vacuum and the fact that the original brand bags cost $5+ each. I happy that this economical alternative is available and that I was able to find it. I will continue to purchase this product as long as it is available. I highly recommend this to those who do not want to pay a lot of money for vacuum bags. I am sure there are a lot of other products on Amazon that we would rather purchase.

I have ordered these in the past and have used all of 10 in the pack with no problem. These are such a great price compared to Miele. I am happy and comfortable to reorder for my vacuum.

It works well once you hook it up correctly, you'll have to wiggle it a bit and check the filter cabin to make sure it is not leaking after 30 secs of vacuum. Make sure to close filter door slowly and firmly to have the filter securely pressed onto the latch on the filter door.

So far so good. Bag fits well and have not had any issues thus far. We have an s2121 vacuum, but the Casa Vacuums bag is definitely smaller and thinner than the original Miele bag which means you will have to replace it more often. Definitely worth a try for the much lower price.

Seemed to do well after first few uses. After 4 or 5th use, my Miele started having issues and collecting debris in the compartment and shutting its self down for overheating. Took my Miele in to the the repair and they put in a factory Miele bag, and issues were completely resolved. Not recommending......

They're just a little bulky, and take some finessing to get into the unit, but they're well made and work great!
