Despite the fact that my son, who loves dinosaurs, has been pining for this toy, I had read the reviews and so decided not to buy this toy. However, for his 4th birthday my sister took him to the toy store to buy him whatever his heart desired. Of course this was his choice. And what a great choice. He loves it. It wasn't as difficult to put together as I had feared, and although on occasion a piece comes apart, it's been easy to put back together. And although not all cars work with it - we have more than enough Hot Wheels cars that do work (and you really only need 4 or 5 that work). This is one toy that all 3 of my boys (ages 2, 4 & 7) love to play with together. Even my husband and a friend of his enjoyed getting in on the action. If you want a toy that babysits your kids - put in a movie... if not, get down on the floor, grab a car, and smile at your son's reaction as the car flies up the Dinosaur and into its mouth.
