This is my review "for now." When they rectify the situation, it will probably be 4 starts or maybe 5. The light kit that I received does not match the instructions for the Lego set. For the tower, the light kit includes lighted 1x8 plates that are supposed to take the place of existing bricks. The original kit uses back-to-back 2x4 plates so unless you have a good way of slicing Legos in half the lighted blocks do not work with the set. They have assured me that this is corrected now but I won't know that until they get a replacement back in stock and sent to me.
I think it will eventually be resolved, but I can't in good conscience submit a higher review since the light kit was made incorrectly or at least not updated.
