Bests & Worsts Reviews from Amazon

My children, ages 4.5 and 2.5 each got two of these for Christmas. They are a big hit. I'm very impressed with the construction, which is of a thick plastic, I can flip it over and stand on top myself and it only flexes slightly on our slippery kitchen floor. They are a good size - an adult of medium build could sit in one. My kids can get in and cross their legs inside too. The shape is great - two of them fit together to form a kind of spherical shape. The two holes are inspired as they love putting them on their heads and looking through the holes. They have found a ton of uses so far! They spin the bilibo and put a marble in and watch it go around. They spin around in them themselves. They have used it as the center in their block building expeditions, as a seat and to port toys around the house. I am very impressed with this toy - I love how it inspires creativity and active play. I would definitely recommend getting one or several! Update - 4 years later - these have stood the test of time. They are not only still in perfect condition, the kids still enjoy playing with them now at ages 6 and 8.
