Questions about Miele power disc

This is an insert with detergent for approx. 20 washes and can be used in appliances with Autodos function.

You need both salt and liquid. It’s like a normal powder detergent. It works well as dishes are left clean and and it leaves a nice light odor on the dishes. Nonetheless it’s very costly and it lasts super below expectations: with 1 eco wash per day except weekends when we had 2, this lasted for 2 weeks. It’s embarrassing the amount of plastic that you throw away every two weeks when you dispose it.

According to the manufacturer, one disc is enough for approx. 20 rinses.
