It assembles and washes very easily.  The two snap levers on each side of the bowl snaps tightly with no leaks.  The buttons are marked plainly and they push easily.  One for slicing/shredding and one for mixing/puree.  There is a button that pulses to chop.  And of course one button for Off.  On the lower side of the bowl it is marked "2 Sides - 1 Slice and 2 Shred"  Another area marked Chop, Mix, Puree.  You remove the lower blade when you insert the disc for shredding or reverse it for  slicing.  This process works so well.  It just whiz's through the process and does beautifully.  It would make a lovely wedding gift, also.
