It looks great once built but building it is extremely boring, some of the pieces will just bend and no matter how much I press them down they bend off, placing some of the panels is rediculous because the sockets wont connect and while im trying to place it on all the tiny pieces are falling off, not to mention I had a few pieces missing including one of the large tiles from the top layer. The book shows where to put the hinges on the top layer and it doesnt actually fit in place going there! I spent about 20 minutes trying to put this tile on with pieces coming off just to realise I had to place them differently to the book for them to work. I cant even finish the set properly now without that tile.
