I bought this and the Sky Tower (of course) after learning of a model based on Blade Runner 2049. While I was expecting to maybe find a new hobby, I actually found frustration. The metal slots can often be too far apart from the grooves, and moving them too far would cause the thin metal to snap, so it was a pain to attempt to move the slabs correctly. I don't feel like I have completely wasted my money, though I shall be cancelling the film projector model I have ordered, and will probably never pay attention to these again.
