Example Input: This bone is nothing more than a big dog treat. I have a 2 yr old Pit who ate through the souper in 5 minutes. After reading other reviews I took it away from him and will save the rest for a later date. I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat. Will not be buying this again.
Example Output: 2

Example Input: I really like this granola - their hemp granola is my favorite. REALLY good stuff. However - it's just too sweet for my taste. Most granola is dreadfully sugar-laden, and other than the healthy ingredients, I feel like I'm chomping on some commercial-grade grocery store sugar cereal... -___- That said, the texture is very satisfying and it is tasty. Just a bit sweet. You've been warned.. ;)
Example Output: 3

Example Input: Makes very good, light waffles. Seems to be exactly the same as Carbon's Golden Malted waffle mix. Only this is more expensive.
