I 'm on my second (the first replaced by Amazon) and it does not work, this device is much too fragile, if a coffee bean is a little hard wham it no longer works, I opened the machine and there I have seen amateurism ... we were used to better with Krups, important components for milling settings is not vulgar solid plastic, grinding wheels of the design is invalid, I will have been able to make the walk warranty but too bad this mill is really to avoid.
