the amazon's delivery in Greece was once again great. I wanted to make this puzzle as a gift for my brother's newborn, cause he is a huge simpsons fan. the low rating is about the quality of this product. I found the locking system and the overall quality really low. Many times I found 2-3 pieces that were an exact match! So this was annoying. I realy like puzzles and I make them regulary and this by far the worst.
