It has fake burrs. It crushes grains and makes mostly dust.
Positive Product Points
Design is tolerable
Negative Product Points
1) Produces mainly dust 2) Pretends to be a burr grinder but in fact it crushes beans by small blocks (that is why it probably makes mostly dust) 3) Non reparable, broke down after 3 years 4) No consistency of grind 5) Grinding either to fine or to hoarse - to small range of settings
It is a fake burr grinder. Beans are crushed by small cubes. It makes mostly dust.
I currently own Demoka grinder and it let me understand that Krups was just a cheat.
I spent two years trying to understand the art of espresso. Krups grinder keep you at the very bottom, you cannot learn how to tamp, how to tune, it is useless. Good maybe for Turkish coffe but I am not sure.
Stay away from this grinder if you want to make espresso. You cannot even repair this grinder because one cannot open Krups, it has no screws that allow you to repair something. The start button dropped inside the grinder and I could not take it out. Than it stopped working.
I went to Electro World in Poland and bought a grinder.
Three Month Followup
I bought Demoka grinder and I understood that I wasted time and money with Krups. I will probably never buy something made by Krups.
They cheat people who do not know how the real burr looks like. I have been making dust for two years and I thought that I have been grinding.
