So far the entire Dragonlock 3D dungeon package of products has been an outstanding Kickstarter investment for me. I have printed nearly 500 hours of 3d products on my XYZ DaVinci Jr printer and have had little or no problems. Although I have only just begun to print the Expansion 3 items I can only assume they are of equal quality to the Basic and Expansion 1 and 2 offerings. All of the updated scans released by Fat Dragon have been useful and print as reasonable Dungeon construction pieces.
