I wanted a combination filter/espresso machine, and this one seemed to fill the bill.
The filter coffee side is excellent; I can't fault it. The espresso side seems to be very good also, but I suspect that it wouldn't satisfy an out-and-out espresso aficionado - but such a person would probably never think of buying this kind of machine anyway.
The machine itself looks good, and, although the housing is, as you'd expect, plastic, it seems to be quite robust. But it's a machine to be installed in the home and used with care - I don't think it would be suitable for office use.
As others have said, the instructions are not up to much. I suggest that, in addition to looking at the pictures, which seem to be incomplete and sometimes misleading, you actually read the printed words, which are much more helpful. One minor point: despite what the pictures indicate, no filter is supplied for the espresso reservoir, though a filter is supplied for the filter coffee side of things. I had this point confirmed by De'Longhi's telephone help line.
