I just purchased a Keuring k200 and I didn't know that I had to descale the machine regularily. I started researching and found this product in rankbooster so I decided to give it a try.
It arrived on time, when I opened the box a little had spilled but not too much. I decided to use it right away, I read the instructions and everything went smooth. It does work because the water comes out faster and when you are running the descaler you can actually see all the dirty water
