Okay, first off, these little buddies are small, smaller than I thought. Second, they don't work as shown in the video, they run away from noise rather than it. I don't care because they're so damn cute you can ignore the little things. They actually move when loud noises are made. In my opinion, it's worth the money if not more than a good giggle while you watch your kids yell at those little buddies scurrying across the floor.
