The o ball rattle is even more fun for little hands than the o'ball which we already had. My little boy (6 months) loves rattles but can't keep a grip on them for long and gets frustrated. He loved the o'ball because he could grip it and chew it and he loves the rattle even more because it makes lots of noise. It's a nice noise though not too loud. His sister (2.5 years old) also loves them and happily shares them with him.
