Input: This kit has a building diagram for only 1 project and that diagram was so poor that my husband who played with these kkits as a kid in the 60s (yes they have been around that long) couldn't easily figure it out - and he rarely has trouble figuring out anything. Otherwise there are 5 other sample structures wwhich have no building instructions and that is it.I put this completely in the category of good idea but bad reality. It is a pity, really, since it would take the manufacturer little work to produce a variety of projects with real instructions. I encourage the manufacturer to do so.
Output:
Negative
