For children ages 8 and above...

Right. And two mechanically inclined adults. And some spare screws. And tools. And about four or five hours. Jeez. You know, I had an erector set as a child and I vividly recall building projects by myself at age ten. I could have literally tuned up my car and changed the oil in less time and with far less aggravation than we needed to build this toy. Thumbs up to my wife for for her determination to finish it. I would have pitched it into the circular file.
