My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.
Bad review

This was perfect to use on our boat during a vacation.

I just received my mouse today - easy set up with Vista 64 bit computer.
