I got these bags quickly from amazon.com and thought they were paper thin or thinner than the 3M bags I usually use from Target. Believe in yourself and give these a try. I think they did well but the 3M bags were clearly better as they were thicker and heavier than these bags. I liked the flap on top to close the dust/dirt bag, which I don't think helped much as the dust still comes out when you try to remove the backing and close the bag. I think the 3M bags smelled better after filling, not that they smelled good, but these bags smelled worse. I never got tired of the Eureka bag because I haven't been able to find one since I bought the vacuum cleaner.
