We have the Leapfrog Tag Junior system, of which this is one of the books, and it has proved very popular with my almost three-year-old. He is already very good with his shapes but this just helps keeps his interest longer.
The instructions on how to download the additional software required for the Tag Reader to "read" this book is simple to do at the Leapfrog website and adding the information onto the actual Tag Reader is simple using the USB cable which is provided but, obviously you do need access to a computer and the internet, which is also made clear when you purchase the books.
I am unsure about how people could be confused that this is a book which requires the Tag Reader for all the additional options because it does say that it's a Tag Junior Book on the cover and on the listing.
