The perfect marble run!

I bought this path for me (mom) and my sons. It was clear from the outset that the building will not be easy. I have quite hurt fingers and it has a few hours and a sleepless night (I had peace) took the building. But the result was truly worth it! Tricky it was in the loop, the 4 times I have not have got done, I had the smallest loop just go away, then it worked and now hums the web. Every now and then you have to adjust a little when the bullets fly off the track. But this happens very rarely.
I can absolutely recommend this path, however, should be an adult help build and be patient. The Quallität is very high. We will grow in any case yet.
A little tip: use the compression of the web parts a towel or something else soft, otherwise you makes the fingers putt and watch with terminals that can ever break when too much pressure. However, it is sufficient material available.
