I bought these egg shakers for my daughter's first birthday. She's been going to a music class since she was 7 months old so I was looking for similar toys we could use and enjoy at home.First, there's hardly any shake in these shakers. There's really not much in the eggs to make a sound. My daughter, who is really familiar with this toy and enjoys the egg shakers from her music class just threw these aside out of frustration.Second, they break very easily. I kept insisting that my daughter try this toy, but about after the 5th try one egg broke in half and I had little black beads all over my floor. I'm scared to think what would have happened if they would've broke with my daughter and I wasn't around.This really is a great toy that kids love. All the children in my daughter's music class love when it's time to dance with the egg shakers. The problem is the way this company makes them. I would suggest looking for another brand name.
