Example Input: It makes good tasting gluten free food... but... like most gluten free food, it's expensive and it's got a slight grit to it. I've made biscuits, waffles, and pancakes with it... a friend made some awesome banana bread with it. it's very good for gluten free...
Example Output: 4

Example Input: That is right, open the bag and just get your nose close and smell it. You know this is a quality product instantly. Some of the tastiest tea I have had and the Oolong and orange are a great mix. Even if you aren't a tea drinker at all, once you smell this tea you will want to try it. I am very glad I bought this product it is a favorite of mine.
Example Output: 5

Example Input: The Amazon product info claims they are a certified organic product.  The picture claims DOP certified.  Neither appears to be true.  The cans I received were just "certified", and it didn't say by who.  There is no USDA Organic label either.  I also knew all these things before I bought them since they are well documented in the Amazon reviews already, so I wasn't surprised by what I received.  On the plus side, they are better tomatoes than I can buy canned in the grocery stores locally, so I'm happy enough with them, and I used reward points from my Amazon.com Visa to buy them, so they were essentially free to me.  Would I buy them again?  Maybe.  If couldn't get any of the Strianese D.O.P. certified San Marzano tomatoes, then yes I probably would.  As I said, they are tasty and I do like them better than what I can buy locally, but they aren't the top tomato when it comes to what I can mail order.
