Have a Saeco Syntia Coffee Machine and am not willing to min. To pay 40 euros for the Saeco-Set with which I can descale degrees 2x - I need min. 3 times a year - that is 120 €. The price of this liquid descaling solution is firstly times cheaper and I can with the 10Flaschen - descale 20 times instead of 2x !!! That means I get to the descaling agent about 3 1/2 years from !!! First two passes have worked great with no aftertaste, malfunction or the like. Be purchased in 3 1/2 years.
