What reviewers are saying

"from the first picture of this thing that I saw I liked it and I didn't really care how much it was going to cost I didn't really care how it was going to be built I wanted it"

JANG's LEGO Reviews

"I really like the Kai Fighter, fun to see a nice red starfighter (or atmospheric fighter), and I applaud the restrained use of stickers and printed tiles, letting the brickwork do the styling."
