We got this for our 6 year old for Christmas this year and we are all having so much fun with it. My husband is the biggest kid playing with this toy.
It is easily set up. You attach it to the top of a door, we used our son's bedroom door. The racetrack comes down from all the way at the top of the door! You may wonder how your young child would be able to put the car on top of this 7 foot drop?! Well, there is a cool elevator that drops down the door and it has a rope on it that your child would activate, by pulling, to get the car up to the top and then it will drop automatically down the track!!
The only downfall I see is that if you don't have the right car, size and weight, the car will jump half the track. We put my sons matchbox car holder, or a laundry basket, underneath it about halfway down so the car will take the whole ride to the floor. Even if you don't do that I think your child would enjoy the toy just the same.
Once the car reaches the bottom of the track it has a way to elevate the end so that the car will jump. This toy comes with a cardboard ring of fire that your car can jump through at the bottom. I give this toy an A+. My child, and my big kid, have so much fun with it. It is well worth the money, in my opinion.
