This is the first UGears model I have been disappointed with. It is far too complicated, some of the pieces are very difficult to remove without breaking them. The distribution of numbers is very difficult to follow particularly when they on on a piece which is the middle of another piece and therefore no longer on a numbered sheet. The tabs are invariably bigger than the holes and need filing down almost every time. The built parts are very difficult to fit together. I have wide experience with 3D Wooden model building and I am not at all sure I will ever finish this one. If I do I know it will not work and will only be "decorative". I will be resorting to glue to hopefully stop it falling to pieces. Reading the reviews I know I am not alone in these comments. A waste of money and it wasn't cheap. Read full review

Some of the pieces were too brittle and the performance was a bit of a let down..
