Pros: You get one dose to administer every two weeks. The machine tells you when to do administer the liquid which is set by the chalkiness of your water which you tell the machine.Cons: How do you know the machine needs decalcifying apart from the machine telling you. Every two weeks makes this very expensive to run. Where can I buy further test strips.

The descaler works so well that it will descale all the items in the box that it comes with. The directions are hard to read though and could be improved. They came all blurry and with the paper breaking apart. I would suggest a bigger font or something that can withstand the descaler for when it leaks. The one that was intact did get used and I don’t have any issues with scaling in the coffee machine. It did give me an irritation on my hands though just to touch the container. Overall I will buy it again but in store.

Great value - I’d recommend keeping on schedule with the descaling when the machine indicates it is needed. I like the larger bottle so you get more cleaning sessions. It is not an easy process without reading the instructions 😁 and I’d recommend you stay close for the whole process.
