I saw my first one a few months ago and swooned --- the two doors work independently of each other so a family of four could put the upper door's load on after breakfast.
Then my friend, a plumber, mentioned fitting one the other day - also the first he'd seen. He said he thought it was absolutely brilliant and couldn't understand why this wasn't the default design for dishwashers - that is, until the blasted thing wouldn't start because it wanted some fussy-dishwasher addidive added into its drawer (prima donna).
Has anyone got one, am I right to be excited about them, and is there one that has now more than 8 options made up of top/bottom/stop/go/hot/eco?
