While I am giving this a 5-star review, there are a few areas that should be noted when it comes to building this kit. Firstly, the bridge is an issue. If you have extra pieces after the build (and you should due to the "support" pieces used in building the engineering section) apply them to the opening in the saucer where the bridge sits or you are going to have a lack of support under it which will cause the bridge to pop off.
Secondly, the outer perimeter of the saucer is held together with elbows and joints. the connectors between the elbows have ZERO bricks on the top of both surfaces, meaning your outer ring of bricks will be held in place at 3 points (port, starboard, and bow of the saucer) with friction fit holding the rows of bricks in place otherwise. My build was missing less than 5 pieces that should have been in the kit but also shipped with extras of other parts. Given that this kit is 3,098 pieces, and Mega Bloks is wonderful at sending replacement parts, this is really a non-issue.
Overall, aside from the listed issues above, this is a fantastic kit to build
