We have a small ball track wanted, in which the balls are big enough. Our daughter has been so far each ball in his mouth. But different with this ball track. The balls are big enough, so that our 10 month old daughter she does not get into the mouth. The balls roll down mostly clean and even little ones you already understand where purely include balls. Since our daughter does not play wild, but good squats in front of the train and the balls can roll, nothing is broken. The colors are beautiful and do not peel off. Unfortunately we do not have the bell pictured, but a cowbell that clatters more than tinkles the spherical output. But interferes with our daughter not. For Wilde Kerle rather nothing that pepper the thing more through the area, for us just right!
