They are utter s**te, nasty construction, stupid design - small waste water container, can't grind beans, only has a manual coffee container, wastes hidden deep inside the case, nowhere to warm cups, no strength control and they can't make a decent ristretto. They are only sold to people who want a Miele label and who don't know what coffee should taste like. They will spend £1750 on a machine then fill it with Douwe Egberts pre-ground pencil shavings.
If you want decent coffee the starting point is a Saeco 30320 Royal Professional. If you want decent coffee beans the starting point is Illy.
Not only is the Saeco head and shoulders above the Miele in terms of the coffee it makes, it's also half the price.
