We bought about a year ago a bullet train for our great son (then 7). But our now 1 1/2 years in building always "between radioed," We have hardly used the big train. Now I have discovered the new ball track for Small and bought the same and we are all (!) Excited. Our little one, the web of course not build alone, I do not know from when it works, but he has a lot of fun because help build, to roll the balls, or simply watch. And the train of course does not fall as quickly how long the large and can always be quickly bring "in form". We still have to buy large plots of packing the launch pad, from the same series. Which brings together a lot of fun and our little one pushes super happy again on the button. The track can be designed differently, especially we like it when the balls again about since arriving where they are launched, and that goes through the corners well (so not have to get up always someone and the balls do not roll across the room) , The small basic package would be enough for me, because it is just a level of "bridges" are, therefore it is also not quite as additional supplements. Too bad, we are waiting for more! The large balls are all different, some with sound effects, and thus also on its own exciting, we have of this, however, already several warehouses. Very good we like the train with normal murmur that sounds beautiful and our little one loves the marbles (probably because he finally can have sometimes). At greatest, but I find that now the Great is newly motivated to build. It builds with the normal ball track elements around it, combining the tracks, without this interfering with the little ones. And the little one does not bother the Great also because he is self-employed. Many special elements of the great train can also be inserted well without any problems, which will last a long time before we have all tasted times. And so we can finally take advantage of the elements of the great train together. Overall, a great thing in usual beautiful Haba Quality. Can we highly recommend it!
