Miele is very convenient to use: it produces little noise and is very precise.These are exceptionally good quality bags for my Miele vacuum cleaner which I was accustomed to buying the bags at a vacuum store due to recommendation by the manufacturer. Since my machine is older I want to make sure that I can maintain its power by using quality bags. I have purchased these more than once from this site and will continue to.We use to purchase the bags at the Miele store because no one else sells these vacuum bags. Now that I can get it online a little cheaper and have it shipped to my house directly, it makes my life so easy. It is sometimes hard to get to the store.I've been using these bags in my vacuum cleaner for many years. They fit well and hold the dirt (no leakage). There is a closure to prevent spilling when removing from the machine.Sturdy vacuum bagsThe product is exactly what I expected.Works wellGreat product!I keep ordering these which is how you can measure my satisfaction.Very nice for my Zeus Mielle.
