The instructions were great but the part tolerance (width) made it uncomfortable for my adult hands; no way could a child <10yo have the grip strength to push some of the rods thru the brick/parts openings. Yet about 1/2 the spacer rings are too loose and slide off the rod instead of holding the bricks in place. My 6yo got frustrated and just walked away, saying ‘you do it’ so instead of a fun build I ended up doing it on my own for two nights. :(
