I managed to snag a 4496 tub (the 50th Anniversary one) a few days ago. Having some extra time on my hands, I decided to count the number of bricks therein, just to determine the quality control of TLG.
Anyway, this set advertises having 1000 pieces. I counted every single one, and figured that I may have 1 or 2 (more or less) than advertised...
... and I counted EXACTLY 1000 pieces!!

Thank you, LEGO! Keep up the great work!!!

P.S. I've had very few problems with missing pieces in other sets in the past, but TLG's consumer affairs department has always come through! It's just nice to see such excellent quality control when opening a new set!
