I got one because it was the only reasonable model I could find with a water softener built in. It lasted a good while (~8 years) and performed well i.e. no hard water stains on dishes. After 8 years it developed a grinding noise in the recirculation pump which pointed to broken gears and a replacement which would cost in the ballpark of a new machine so I replaced it.

The design itself has some "German overfeatured" idiosyncrasies to me. Like, when the wash is done, a little stick extends out of the top of the machine pushing the door open to vent. But then, when you tug on the door to open it, you can hear a little geared motor spin and retract that stick. Just more stuff to design, add to BOM, and to break.
