For its first birthday, our daughter was given this marble run. At that time she was the new toy is not really interesting. Today it is at 17 months, and also creates problems to put the male and car to the track and plays increasingly so (which my husband and I still have a lot more fun). While rummaging in Amazon I marveled not bad today, when I saw the high price ... However, this is really a nice, stable toys - especially in contrast to other ball tracks also quite large, the balls can not be placed in the mouth. Therefore, I would make up my mind when buying for this ball track. We will eventually continue to give back and they will certainly survive a few generations.
