We bought our first roller coaster 6 years ago for my daughter.  This was the best purchase ever.  We have kids come over all the time and play on it the whole time they are at the house. We now have a 2 year old and he is just beginning to be able to use it himself.  He can push the car up the coaster and turn around to sit down. He needs help to push off so that is good for me to watch out for other kids for him.  We have a 6 month old now too and I know that this item will last for the next 8 years minimum for her to use as well.Again.. Best purchase ever!
