Starter pack with everything you need as a beginner ... the son is very excited and can already alone build the rails together ... for a 4-year-old, however, not simply because the Kunstofflaschen not particularly are stable. The setting up of the train is not entirely without problems ... that's asked Father ... but go may only son. The rails are hardwearing ... unfortunately there are few accessories for these starter kits .... would ideally that you can buy more individual trains .... and not only the whole Starter Set. As a birthday / Christmas present ideal ...
