Ex Input:
When I bought this book I was expecting more information. Most of it I've had heard before and could find very easily at the library. There are a few helpful tips, but overall, not worth paying for it! Unless you're someone who knows absolutely nothing about getting older, then maybe it's worthy - to save you some money. It only takes me 10 min to write my thoughts on every topic in the book.

Ex Output:
Good Review


Ex Input:
I returned this item right away. It did not work for my husband at all. He could barely hear anything. And no headphones, just the ear buds that come included. Not worth what it was...

Ex Output:
Bad review
