Separate parts on the base don't hold up. I had to glue them together so the weight of the structure wouldn't split them. I made the first build following the instructions and made it according to the color. The heavy colored stuff was the wrong color, and while it's a minor change, I got two sets of blue instead of blue and green. The pieces were all there, just not the colors. One of the spinners didn't spin, the plastic was molded too tightly together and was applying more pressure than the ball can generate to get it spinning. The balls just stick on it. I probably should have just bought the brand name. The guy on the front of the box looks like someone just shot his dog.
