Textbook came brand new in wrapping, along with the Mastering Physics key.  Book seems to be perfect, and have everything I need for my Physics class, but I only rated it 4 stars because of one (minor) issue; and I would give something like 4 1/2 stars, but I can't.  The issue I have with it is that the book smells pretty...weird.  I don't know how to place it.  A friend of mine said it smells like cat piss, and I'd say that's close, but I'm not sure.  There doesn't seem to be any source of the smell.  The smell is just on the book.  Maybe that's normal, but I have no clue.  Either way, it doesn't really affect me or the usefulness of the book in any way.  I'm just glad I was able to get what I needed MUCH cheaper than my college bookstore charges for it, and brand new, no less.
