Query: Great idea, great toys, doesn't fit

I think they made a really great toy. I like the idea of detatchable toys I can rotate or even substitute in. What is frustrating is that adjustability was not a concern in their design of this product. It definitely does not fit on the Peg Perego Primo Viaggio Car Seat nor the Peg Perego Aria LB stroller. The clips on either end of the arch do not open very wide. I was very disappointed though--it would have been a great concept.
