The guide is really very good and explained all the necessary steps because other companies could learn a lesson! I have all the steps of the guide repeatedly carried out and was curious about the result. The first two weeks I was pleasantly surprised. The coffee arrived back completely dry in disposal containers. After the two weeks they were then but again aqueous. Nevertheless, I am satisfied with the service kit and can recommend buying. The kit is not expensive and clearly explained how to look after the coffee machine properly.
I have now an extra tube 'fat' ordered on the Internet and fats the machine again after a month. So the coffee remain sufficiently dry. However, since the effect of this service kit lasted only 3 weeks at me, there is a star deduction. Incidentally, the set came to me as a letter, which I find very convenient because it can be simply thrown into the mailbox.
