[This review was collected as part of a promotion.] Really, I would say this is 4.5 stars. When you purchase this toy, make sure to stock up on size D batteries. Otherwise, you're going to have some disappointed kids until you can get to the store again. Overall, this is a really nice set. There are a lot of options to choose from to make your track. You can pretty much set it up any way you want. There is an issue, however, with some of the pieces not fitting together snugly. Every now and then, this will cause a car to go flying off the track when it hits that spot. So do make sure everyone around is aware of the possibility of projectile Hot Wheels, haha! The kids absolutely loved it once we got some batteries. We've had it for two weeks and they've played with it every day, and I must have seen at least twenty different configurations of the track. They especially enjoy racing with a double track (our police car is the fastest) and lining up every single Hot Wheels car we own at the same time to see how long they can run through without crashing off the course.
