It is a rattle that makes noise (Not annoying) compared to others that don't make any sound at all, and for me, that was the goal, to capture the interest of the little one not only when we play casually but also when she is extremely restless or crying. It has an easy grip, and the balls move a lot inside the transparent section that is Sophie. However, it has one downside, the transparent part is hard, resulting in the child hitting her head when she shakes it vigorously. So every time I give it to her, first I stand in front and make sure to give it to her from the soft side that makes a crinkle sound. I believe this will be a problem, of course, for every plastic toy, which is why I prefer fabric ones now that she is still very small. Overall, however, as a product, it is worth it since she likes it.
