Eureka Style Micro Lined Replacement Vacuum
There's really nothing to dislike, i.e. no "cons" that I've identified, about this product/ these products. They are exactly as described, and as prescribed by the manufacturer, for use with my Eureka upright vacuum.
Just one point I learned, by trial and error, that other users might find helpful: when attaching a new bag, I find it is easier to lay the vacuum down flat on the floor. This way I have less trouble slotting the cardboard paper bag collar into the slots on either side of the back ledge, while at the same time inserting the hose adapter (outlet) into the bag's collar. I hope this makes sense! But I think you'll find it clearer if you have the vacuum in front of you, with the bag cover off.
My personal experience is that similar, non micro-lined replacement vacuum bags aren't as efficient as the ones being reviewed.
