Example Input: This is by far the best hot cocoa I have found yet for the Keurig. I love the assortment and the peppermint is my favorite. I would give these try for sure if you are looking for some hot cocoa K-cups. All the other selections for hot cocoa that I have tried were just okay tasting. These are AMAZING!!!! LOVE THEM! I will order these for sure again!
Example Output: 5

Example Input: It may be all natural but it didn't have a natural taste to me.  The can size is small and the calories were more than I thought there should be.  I like the mild carbonation ok but I wouldn't switch from orange juice.
Example Output: 3

Example Input: Great value for an infused truffle oil, however I enjoy the White Oil better for basically the same price.  I'm sure I'll use it all up and then just order that one instead next time.  They're both good.  Love it in mushroom quiche or garlic mashed  potatoes!
