Junk
I have not much to add from what everyone else has said. All they have to do it increase the run time between shakes to allow the cars to actually finish the race and this would be a toy that is fun to play with. The instructions tell you to shake it at least 7 times for maximum run time. That gets you the 3 laps if you are lucky. If you only shake it once or twice it will go around about 1 time. You do have to shake it pretty hard for it to work also. My 2 year old likes to play with it but only for about 3 minutes because you have to keep picking the cars up to shake them after about 3 laps. He gets bored with it and goes onto something else. That is about as long as I can stand it as well.Neat idea, bad follow through.
