My kids love fitting the triangles and squares together, and the gears actually stay in place when they crank them. It's sturdy enough for our daycare center, and I've seen them problem-solve for half an hour straight trying to make the whole thing spin.

We bought these for our son's fourth birthday, and the gears actually spin smoothly when you connect them to the triangular base pieces. He's been figuring out how to make the whole row turn at once, which feels like real problem-solving play.
