It's a really beautiful model of the colosseum. It took me a lot of hours to build this and the experience is really there.
The building process isn't really hard to follow, but some parts me be a bit confusing so just look carefully which pieces you need.
This is my first UCS/ Expert Creator set and I can't talk enough about how good the model is, because it's an Expert Creator set you can't play with this model of course.
For $500 it's almost a steal in comparison to the UCS Millenium Falcon, which is $850 and has around 5000 pieces. This model has 9000 pieces instead for $350 bucks less.
So if you want a really nice and big display model of the Colosseum or you just want to take a lot of time to build a set. This set is for you.
