Since we are using the machine almost exclusively for "ordinary" coffee, we get us our pads at Aldi. Nevertheless, you should be durchrechnen carefully before purchasing if you do not plan pays ultimately.
If, like us has had a bad experience with a machine of another brand be (lid had to be forcibly closed, the tank could be seen only with an effort, during scalding splashed boiling water out of the cover), which is to feel rewarded with this machine and enthusiastic !
