I bought the eggs for my 10-month rattle daughter, she loves to play with it and also every toddler visit was very impressed by the rattling eggs. The eggs are very well made, hold several falls so far readily from! Even in the bathtub or pool are the eggs welcome companion. The eggs sound in 4 different volumes, where 'extra-loud' the designation makes all honor. Too bad that the Rasseleierset is not very colorful (white - gray - red - black). I'm going to buy more Egg Shaker as gifts for my nieces!
