Well, I must say I was disappointed in this. While it LOOKS very cool, the loop RARELY works right, the plastic cars are junk with wheels and axels that don't even spin well enough so that if you DO make the loop, they stop short. The ferris wheel and plane ride don't stay attached, so they are CONSTANTLY popping off.I like a LOT of their other products, but especially for $33 with delivery here, I'd avoid this item. I enjoy the GARAGE, HOUSE, and ZOO so much more, especially the ZOO. DO NOT BUY this item.
