Schön. Einzigartig!

This is a good price, I've seen the same model on sale in highstreet craft shops for three times the Action price. On the box it indicates that it takes 8+ hours to assemble; a zero can be added to the 8. I'm about half way through building my marble run, it's a great challenge and worthwhile project for the mechanically minded such as myself. The many small JO3 pegs are fiddly to fit into place, I had to slightly chamfer leading edges using the emery paper provided in order to locate them in the holes. Whoever designed this marble run and figured out the layout for all the parts on the boards must have a massive brain. Excellent video :)
