Here were told a lot about the device, so I will confine myself to the basics .... First of all, we have in our household / family / friend circle already 3 Krups KP 5000 Nescafé Dolce Gusto Circolo in operation, so we already know our way around the handle. But is not really difficult - Unpacking connect heed program for the initial installation and the first cup of coffee, nothing stands in the way of .....! Conclusion: device looks good and what makes her in the kitchen. The water tank, however, is the "Achilles heel" of the device! It is simply sized too small and quite cumbersome to fill and lock back into the machine. For a star deduction! Also, it seems to me the operation but a bit noisy! The Dolce Gusto and Krups coffee concept convinced otherwise already. Apart from the above-described small errors a great device!
