Review on Vibrant Red MOLUK Bilibo: A Must-Have Sensory Toy for Children by Pat Haberman

Our kids loved them an immediately started spinning, flipping them over and balancing on them, using them for cars etc. They spin well on carpet and tile. Even as an adult I could squeeze in and spin with the kids. I think these are better introduced at a younger age, but you definitely need to know your kids- if they are imaginative and like balancing then they will likely like these.
