SmartMax Mega Ball Run 71-Piece Magnetic STEM Building Set for Ages 3+

My 5 year absolutely loved it played with it for hours left it alone and came back to it again through out the day!

The parts are big enough for safety and easy to connect for young children, but stimulates the minds of all ages to have fun and build creations at various levels of ability and skill. Structures can be very simple or more complex, requiring trial and error and problem solving. More then one child can play at a time, promoting sharing and working together to achieve a common goal. And most important, MegaBall Run is fun and can occupy children for a considerable time.

Perfect for my 4 year old. Keeps him so busy building his own little structures

My grandson has fun rolling the balls through the tunnels putting it together taking it apart Hours of fun!😊

I ordered this for Christmas so I haven't seen the reaction of my grandchildren. They love the basic set (and learned how to make sturdy structures), so I am expecting them to find creative ways to use the tubes and send balls in all directions! I already have 2 of the basic sets and am looking for more different sets to keep adding for variety of their structures and play.

My grandson had asked for these for his 4th birthday. I cannot get the pieces to stay together so we never got to build the ball roll that he wanted so badly. Disappointed.
