My son has other Magtastik magnetic balls/sticks that he really enjoys building with. We thought this roller coaster would be a highly entertaining toy for him as well. The Wonder Coaster features a Ferris Wheel that has a handle that turns the wheel and magnetically lifts the cars onto a track. There is also a tunnel the balls go through and magnetically get hands and faces attached.
We like this toy because it is so colorful and entertaining. The music is fun and the watching the cars roll along the tracks and run into silly faces and hands causes much laughter. It is easy for our toddler to operate the ferris wheel and tracks.
We dislike this toy because the tracks fall apart so very easily. We are constantly putting the tracks back together and encouraging our son to not lean on the tracks. It is not very toddler-friendly in that aspect. I don't think the price is right for a toy that requires so much maintenance.
