Review on Revolutionize Puzzle Building with Ravensburger Big Ben Technology Perfection by Brad Lovro

This brand of puzzle is probably the highest quality and we have bought over 20 Ravensburger puzzles. I bought this puzzle to keep the kids busy on Labor Day while we visit relatives. Imagine kids wanting to build Big Ben, and when they reach the top of the tower, the pieces of the puzzle don't fit. Looks like they didn't include the correct parts for the top. Only about 10 pieces but it was a disaster. The kids cried and demanded that I give it back and take another. I told them that if there was an error in the packaging of this puzzle, it was most likely in other similar boxes. I wanted to send it back to Revain but there was no wrong piece of puzzle error and I didn't want to argue that pieces are missing etc. Where is quality control? Buy another puzzle.
