Once DD14 built to "spec" (which, truly, she did enjoy quite a bit) the item lasted about until she could see a way to make a few "improvements" (often to make it, er... more tactically useful somehow) and all bets were off. Sometimes minutes, sometimes a day or two.
She has also had quite eclectic tastes, so we have bits of Harry Potter LEGO with bits of Indiana Jones, etc.
They live in a giant sturdy box that came from an American Girl purchase many years back. The item, whatever it was, is long since packed away, but the box lives on in my DD's room, filled with LEGO bricks and bits.
