I was only critical, the water filter on. But it's actually seen a clear difference in taste! Wow! Descaling takes over the machine itself and I think the product is also good. The tablets I use more bad than good, because I simply in the inner workings of the solution "inlay". The fat is useful and makes sense, but the content in this Mini-Tube is already an impertinence! The rest I could not use because there is no opening for the pipe cleaner in my model exists. The rubber I have not had to replace.
