The quality is really good.
Baby uses it all the time.
This is a well made baby toy. My grandson loves it.
My littlest grandson likes this little ball. It is very sturdy and withstands bounces on the floor from his older brothers. But the little one chases it and pushes the buttons and loves the music! For his age (1 year), it still piques his interest and is one of the first he pulls out of his toy chest! I would recommend it for the age appropriateness, but would probably not pick it for much older than a child a year old.
It's a completely hard ball that sings and lights up. It's saving grace is the pop up monkey
