Disappointment for both children and adults. While the subject could be very interesting, the few and poor quality contents of the box, as well as the poorly written instructions, do not help someone to engage.

Disappointing!
First of all, its contents are few and cheap, contrary to its shiny cover. The construction cost should be a maximum of 2 euros!
The problem is that even the instructions with the tricks are not helpful, you struggle or even fail to understand what it says, let alone a child. Furthermore, many of the tricks require you to already be experienced, as it asks you to do something secretly from the audience without telling you how. (e.g. "Hide a ball under the cup without being seen").
Finally, the link it has for videos that show you the tricks does not work!! I sent an email to the company and they sent me a link from a foreign, unrelated channel on YouTube.
