Comments about Product: Our family of five (1.5 years-11.5 years)love this marble run system. Yes, it can be tippy, but the older children learn good balance building skills to make non-tippy designs and the younger children learn to be careful because they love the large layouts. It is a great toy for to engage all of our children at the same time at their differing ability and skill levels. We have several different sets.
