지오스마트 - 솔라 스피너

My kid spent a whole afternoon building different shapes with the squares and triangles, and the solar panel actually made it spin on its own near the window. The pieces feel solid and click together securely, which I appreciate since my toddler likes to grab everything.

The magnetic pieces snap together so firmly that even my 4-year-old can build the spinner without pieces popping apart. We built it on a sunny afternoon and watched the whole thing rotate steadily on the windowsill. The double-safety system gives me peace of mind while the bright colors keep the kid

The magnetic pieces click together satisfyingly, and the solar panel actually drives the spinner for a good few minutes in direct sun. I just wish the instructions were a bit clearer on how to align the gears for the spinning motion.
