I do not understand why many believe that the mill would be noisy, it is quieter than my previous mill. kaffebohnen are hard and it happens to be not easy to crush such a roasted bean, I think because the machine quickly served, the volume is fine, it is ground so only seconds and not hours. Mug Volume adjust grinder to 1 and excellent espresso quality. enough for a double espresso, if you set on Mug Volume 2. I have beem joy portafilter machine, semi-automatic. the top espresso, cappucino the top. the coffee smells wonderful. fast grinding. good design. the removal of the collection container is very good. no dirt. easy removal. you can see the rest amount of beans very well. have long comparisons and tests read and am always in this Severin ended, I do not regret the purchase. the crema is wonderful with the ground coffee. Freshly ground is better. once found the right grind and then set the cup amount you really need only briefly press the button, and seconds later, the ground coffee is ready. in the milling is no dirt swirled around, everything ends up in the collection container. a really neat thing. even when taking there is no dirt, everything stays in the pot. now I have to find for me only the correct type of coffee. I have my coffee grinder found and can really recommend it. 5 star plus
