1- Unreliable: the life of my mill was 3 years (use 1 times / week) !!!
2- Meules not terrible: no matter the setting, I still had partly too fine grind (coffee powder) that passed through the filter of my Bodum.
3- The unit stops incessantly during grinding, the vibration moves the lid and / or container which causes the machine stop ... We must constantly re-press the lid and restart the mill .
Without giving a bad image of Krups (they have excellent products in the range kitchen), this coffee grinder is of poor quality and in conclusion, my next mill will unfortunately other than Krups ...
