I have been meaning to write a review on these for months, we love these! She uses them in the bath and always carries them to her room too. We have even brought them in our pool. They do not accumulate water inside, I saw another review that said they do - they have not for us and we have had them for at least 3-4 months. 10/10.We gave these to our grandson. He loves them. No holes for water to get in and get moldy. Recommended.Fun for bathtubs with toddlerMy baby who just turned 1 seems to like them, but they aren't his favorite toy. He likes shaking them and seeing the things spinning inside, but I'm annoyed since the crystal clear plastic is now foggy after only a few weeks of daily use in the tub. Wish the plastic stayed crystal clear....they’re a good size, they make cool noises, and i just think they’re super coolMy grandson just loves these!!I'm giving these as a gift.Love them for my babySadly we only received 2 of the 4 ballsA mi bebe de 7 meses le encanta jugar con ellas en la bañera, ya se nos han caido varias veces y hasta el momento han sobrevivido!Muy buena calidad de los juguetes, mi bebe los disfruta mucho sobre todo a la hora del baño, el pedido llego en buen tiempoRecibi solo dos de las 4 esferas, la publicacion indica que se reciben 4 unidades y solo llego un paquete con dos esferas.NUNCA ME LLEGO
