Ridiculously overpriced tablet product made from the cheapest materials that can exist in this world. While these materials may be nonexistent on the Moon, here on planet Earth, vinegar is abundant! Another proof of the greed of the people in multinational manufacturing and not only. It does its job, but the tablets, when I open the blister to take each one, are crushed into powder inside their respective compartments. I don't know if this happens only to me, but 2 packs I bought with a 5-year gap were the same in both cases. The tablet was ground into dust! This is very problematic because it doesn't fit whole into the place it needs to go, and I had to use makeshift solutions and funnels to pour the powder inside. Nevertheless, I had to unscrew the cap again (it has a small screw of a strange star-shaped diameter, and fortunately, I had such a screwdriver!), so I was cleaning it with damp cotton balls and skewers to remove this dangerous powder so we wouldn't ingest it and get poisoned... Shameful things, especially with such outrageous prices for a maintenance product of an expensive coffee machine! Judge for yourselves what I'm telling you...
