"Although the set has almost 800 pieces, it still took me a fair amount of time to finish due to how many small pieces that are included with this set. The paddles alone took some time as they required many of the same repetitive pieces to build. The reason I did not give 5 stars is that the smokestack closest to the cabin has some friction involved where it keeps it from freely moving up and down. I double checked the instructions and this is not an error on my end. Perhaps the grease from my fingers rubbed off on the bricks which touch each other as the smokestack goes up and down? Nonetheless, it is kind of frustrating."
