We have a Saeco coffee machines in the office. The original Saeco liquid descaler costs 5,99 Euro per 250 ml. This 250ml should be fully used for descaling. The Flüssigentkalker of espresso contrast vision costs the equivalent of 4.20 euros per 250ml bottle, but is highly concentrated, so that only 125ml used for descaling and therefore an application only costs 2.10 euros. In conclusion, I can not tell the difference to the original descaler. Thus, the present Entkalker gets full marks, also because of the good value for money.
