Save yourself the trouble and never buy this mill because it's a waste of money and your time.
Positive Product Points
It grinds beans into something that could be usable in a drip machine and seems to look good (outside appearance).
Negative Product Points
If you plan to use it for real espresso - throw it away immediately. Ground coffee is uneven, blocks the machine 9 out of 10 times and regardless of the setting it produces big particles and powder at the same time. Dark roast/oily beans are blocking the machine, thus you have to be standing next to it and shake it every now and then if you want it to continue "grinding" ("grinding" because it's relatively far from grinding).
If you have a non-pressurized basket in your portafilter - this mill will never make something usable/drinkable/cremable. There are "success stories" regarding modding it - but honestly - better start saving money for a real grinder. I recently got a Rancilio Silvia and what I am doing for now is that I am buying beans in the grocery shop and I am using their big burr mill to have something of a kind of pre-ground coffee (and yes, I am getting some results on that grocery-pre-ground coffee). Never ever put expensive coffee in Krups mills.
I got it in an electronics supermarket where people have no idea about what they are selling. That was at the moment when I was slowly getting enough money to develop my coffee addiction skills.
