Query: Don't waste your time or money on this toy.

This toy looks like a great idea, but the execution is terrible. The toy cannot hold my very petite 9 month old, it either slides out from under her if she pushes on it or topples over on her if she pulls on it.The assembly is a big pain, and it wouldn't come apart without a fight. We took it apart to return it, and I broke every nail I had trying to get it apart again.Finally, and most frustrating, the balls would not roll down the groove all the way because of these bizarre overhangs on the main "pipe" of the toy. You have to knock the balls past the sticking point. Very poorly engineered toy!!!
