When Trihorse Kugelbahn the wooden balls are so great that it would be very unlikely that a child gets the ball in the mouth and can choke on it. According to mom and dad there is no concern.
Although the small "terror-worm" is only 7 months old, he already has a lot of fun to watch as the balls of level walking to level. I think that the little one will have found in a few months, how can even roll a ball.
For processing the web:
The train was delivered almost fully assembled, you just had to screw on the two feet.
The build quality is top. This part is very stable and is processed perfectly. The balls do not fall off the track and stopped at the end.
I missed only a bell or sound stairs as final.
But since the balls (or star and car) rumble already fairly loud, it is probably a relief for the parents, when the web is not produced additional noise.
