The fit overall is really good. Almost snaps together. A little filler and sanding is needed on the seams, no more than other kits. The instructions do not mention the little magnets that fit in the lower hull and the command deck. These powerful littlle buggers help to hold the detachable command deck onto the the main hull. I've gotten it together and am in the painting stage now. So far, I think this is a really well done kit and it's not expensive either. Oh yeah, while the parts are numbered on the sprues, they are not referenced with numbers in the instructions. But as there are not many parts it's not a problem.
