I have one, it is awesome; it’s just a plastic capsule that clips in, so hard to really break. The dishwashers get things super clean too.

I don’t think it is more problematic but it is expensive IMHO per load. I have had a Miele dw in my current home for 9 years and really like it. I bought a Miele DW for a second home with Auto Dos and it was installed at the end of March. It came with one disc and a voucher to get 6 more free. My first disk lasted 19 washes before I got a notice power disc was empty. I ran several small loads not that dirty so not sure it it really cuts down on the detergent for a small lightly soiled load as a disc is supposedly about 20 loads.

A few observations about the app that tracks the amount left. The disc full weights 438g. The detergent weighs 400g. If you take the disc out and put it back in before it gives you the empty notice - it starts over saying it is full.After a power failure the app said the disc was full again and after the next run it was empty so you can’t rely on the app to give you an accurate detergent level. Doesn’t really matter but comming from a software background I felt a need to test it out. The detergent cleans well. There are youtube videos on how to refill with your own powder detergent. Not sure I will continue to use autodos after I expend my supply. Given the rebate offer at the time it did not cost me more to get an autodos model. I would not pay more just for that particular feature.
