Example Input: These truffles are not as great as they are made up to be. I thought for the price they would have a greater taste, but they didn't have much taste at all. They are not worth the price, but had to find out for myself. I will not be buying truffles again, and I'm not going to spend over $10 for a fresh one.
Example Output: 2

Example Input: I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!
Example Output: 5
