All I can say is Wow! My daughter received this for Christmas from Santa and it is something else! She is 9 and can't put it down. Extremely durable and well made. Excellent play value. It is extremely clever and sophisticated, yet basic enough for young kids to *get it* and feel a real sense of having discovered something special. Leads them to **think** in new ways by exploring all of the little hidden inventions that some magician had to come up with to create these illusions. Worth every penny. I wasn't expecting much for this amount of money, but it FAR surpassed. How do they sell this for so little??
