So, I got one from LIDL for 27Euro.
600ml basket, selectable times, 50W power and 46kHz operating frequency.BLUE LIGHT!!!!!
I have cleaned, using water, an LM Micra (99 USA) and some knives, cutters etc.
Works fine, cleans the deposits well, though it does not remove stuck on rust or resins.
Maybe if I add some washing up liquid, as sugested for the removal of heavier oily stains it will be better.
After I finished I did another self-clean cycle to clean the cleaner.
