Cons: poor design, not enough thrust to move cars through the loop
We bought Team Hot Wheels cars specifically to run on this track in hopes that these cars were designed to successfully make the loop of this track. No such luck. My son and I are extremely disappointed because the cars barely make it up the loop before they fall to the ground. It's sad to hear your son playing and sighs abound when it won't work as promised. We've checked all the joints on the connectors to ensure proper setup. Believe me, we want it to work.
