Directions are extremely vague and some steps out of order. No exploded view to ensure proper assembly. Has a scale saying 1:1 which they shrunk down to save money on printing so you have to guess the right part. All parts put into same bag instead of by subassembly. Have to use other pieces not in set to get push rods to work properly and not fall out. The tolerances are horrible. Had to use a mallet to drive numerous pieces together. Other ones so loose they don't do what they need to. Had several damaged pieces that I replaced with various leftovers from other sets. Overall aesthetic looks great. Fit and finish not so much.
