I was using this until recently. I had two grinders, one for drip coffee and one for espresso, but I've bought a machine that can do both, so I'm selling this one. I'm not running a cafe, so I didn't use it very often. The hopper was hardly used. It comes with a tool that uses air pressure to push out the remaining grounds. It will be shipped in the original box. You can search for "EUREKA MIGNON MANUALE" on YouTube to see how it works.
