first time buying an off brand lego.so far not a great experience.I had 5 or 6 pieces missing (going to send an email) the instruction where printed so small that I pulled the PDF from lego (if you do that be careful at the end they made some changes at step 415 ,416) and overall the fitment of all the pieces is ok .

No missing pieces. Bags all in order. Last steps on saucer were tough to connect. Looks great when done. 3 minifigs very bad.
