"Tightrope Terror" was just that; a terror. Hard to believe anyone got this toy to function as promised in the ads. Here's the rundown; the towers and the bases snap together with thin, cheap, hard plastic that is easy to break. Once together, you can't get them apart again to store back in the box for fear of breaking them. In order for the toy to function at all, you have to put heavy piles of books or weights on the bases to keep them in place. THERE IS NOWHERE ON THE BOX THAT STATES THIS. And the pictures don't show it either. If you are lucky, and the towers are perfectly aligned with each other, and you pull on the ripcord hard enough, the vehicle might make it across the string. Even when it does it usually crashes as it enters the second tower. The furthest I got the car to stay on the line was about four feet, and as soon as it hit the tower landing area it jumped off the track 3/4 of the time. My son got this toy as a gift for his birthday. Thank goodness it came with a gift receipt. The car by itself was cool, and as another reviewer posted, I would get these by themselves and forget this set. As an aside, reviewers will soon be required to state when they are being paid by a manufacturer to review their toys as so many positive reviews come out for items that are simply junk. BEWARE.
