"Let me start out by saying that this was one of the absolute best Lego sets out there! Some of the features include mini cars, and a working Draw Bridge. To save time while building, organize all the pieces before attempting to build, and build both towers simultaneously. This should decrease the time significantly. It took me roughly 3 hours to organize all the pieces and 10 hours to actually build. The final product comes out to 40" in length and 17" in height. I am using mine as a centerpiece on my coffee table in the formal living room. It wasn't too hard to build either, as I had taken a 10 year hiatus and only recently have gotten back into Lego's as my 5 year old son enjoys playing with them and Legoland: Florida just opened. I recommend this set for any true collector."
