I bought these for my 3 year old grandson. He is into everything dinosaur ???? right now. Also monster trucks. These Dino-trucks bring the best of both of his worlds to him! They are small enough for his little hands to hold on to, yet large enough to to blaze the trails across the living room floor. I love that he can pull them backwards a bit and then they ZOOM across the room to the delight of his little sister. I might buy another set and his into them for when she grows up! This purchase was DINO-RIGHT!!!
