I love the look of the model, even though it is very unstable. However since it isn’t their model anyway it doesn’t really matter.

What does matter is that there were several important pieces missing as well as HALF the instructions. I had planned to buy the original creators instructions anyway to support him since I was building his model, but half the instructions missing is still a big deal.

There were also no stickers included, which, while understandable, does diminish the quality of the set.
