I loved the idea of this water table. My kids love watching balls go through mazes so it looked great! I'm extremely disappointed, though, in how it is put together. The yellow tower isn't actually attached to the base at all. It has some notches to help it fit in to place, but nothing to hold it there. My kids (18 mo and 3 yes old) are constantly knocking it over at just the slightest touch. Basically, it's only functional as a water table, not an interactive ball toy. Feel like I wasted my money.
