The quality, as the Dolce Gusto prepared the coffee, I find very good. However, I already had in the second week of disturbances at the machine, in other words there was by no water. That made me very excited and then I had to look in the tutorial on how I can fix it. The only solution was finally cleaned with a small needle the flow. That such a thing was necessary after the second week ?! I am the only user of the machine, ie not in the office, bring in 50 people daily coffee. Before that I had a Tassimo, except the lime never had a failure, because I just did not quite make the coffee tasted so good.
So my conclusion, quality of preparation very good, unfortunately I have probably caught a Monday device. It may be that other devices / models of the Dolce Gusto are better, that was my first experience with this brand.
