Title: Cheap and frustrating
Review: What a disappointment. Everything about this marble run is cheap. We've assembled three of the tracks on the box so far, and none of them work like they're supposed to. The inclines aren't right, so the marbles end up getting stuck. The yellow corkscrew pieces in particular are an issue - they've got connector pieces that are supposed to hold them together, but they're so cheap that they just keep snapping apart. The quality of the plastic feels worse than a toy you'd get at McDonald's. Buy something else.
