Tobbles Neo received enthusiastic approval from our evaluators. The toy consists of 6 spheres and a base. The spheres are indented on one side so they can nest in to one another making a tower. They can be stacked straight up and down or turned at different angles to make a wobbly looking tower. You can spin them and roll them and they even seem to feel good on sore gums. The material the toy is made of is very comfortable to the touch and easy for baby to grip and hold. The bright colors and modern design make the Tobbles Neo very aesthetically pleasing. Even younger children, including our 10-month-old tester who cannot stack the spheres yet, liked to knock them down, throw them, and chew on them. He also likes to hand each individual piece to his mother and watch her very intently as she creates a tower. This toy is made of durable high quality materials, ensuring years of entertainment for children as well as adults.
