After initial teething problems, the machine worked perfectly, the coffee tastes good. With this coffee machine you have after scalding except the cup clean nothing each time, that's fine. The red string does not bother me not only, I find them original. Unfortunately, the machine from 23:07:15 (after 6 months) - apart from fast red flashing - no longer worked, a descaling attempt failed, unfortunately, the 'questions to the machine' on the NESCAFÉ Dolce Gusto site provided no information. I'm going to order quite sure any more coffee at ISPs.
