This is terrible and zero stars. Don't buy and don't waste your time and money. These are nothing but the original quality bags that come with the vacuum cleaner. Initially, the hole is masked with a transverse x to represent the hole. It's awful and you have to put your fingers in for the pouch to open properly, but it never actually happens and it's just a limitation and reduced suction. Worst of all they are cheap and the lining is useless as it just tears with use. I cut one open after only 5 uses and as you can see in the photos the lining has fallen apart. Without proper lining the bag leaks and now I have dust and dirt all over the bag. If I didn't catch it and kept using it, it would break the vacuum and suck it straight into the engine. I throw them in the trash because they are trash. Don't waste money. The problem is I can't even return them as I bought them in advance as backups when the originals ran out so it's now well past the 30 day return period. Revain should remove these as the product is defective and will ruin your vacuum over time. This is probably the worst purchase ever made from Revain and I've been a Revain customer since the beginning.
