WHY I LIKE THIS TRUCK:
-The truck works with the included balls and other balls of similar size. So, you can load up the truck with even more than 3 balls.
-The buttons say a variety of phrases, not just the same ones all the time.
-And the string, my baby loves these strings on trucks/cars. He loves the fact that it moves the truck, it's a moment of "wow" for him.
-Pushing the ball through the hole is coming along, he is learning how to do it. I also think he likes the cause and effect lesson. He totally looks for the ball when it pops out through the hole.
-the price! it packs so much entertainment for such a small price!
