"The set was really fantastic, I gave less than 5 stars because of quality issues. We received an older version of the instructions, with pieces for the newer version of the set. This led to a great deal of confusion, when it appeared we were missing a number of pieces. Thankfully I checked the newest version of the instructions, before reporting the pieces missing. The between this issue and a defective piece in another set this Christmas, it appears Lego is having some quality control issues. I've been building Lego sets since the mid-1980s, and have never seen anything like this."
