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: I have 2 husky/shepherd mixes. The first is 13 months and has a finicky stomach - if he eats too fast, drinks too fast, or eats anything out of his routine, he would bring it back up. He also wouldn't eat more than a few nibbles at a time. The 2nd is 7 months old and came to us with severe diarrhea (vet's food didn't fix it either). He would eat anything and everything if we let him. Within a day of both dogs being on Harmony Farms (No fasting, just a quick switch), both dogs digestive issues are gone. My oldest (the finicky eater) is healthily eating his meals without pause or hesitation. My youngest has solid, regular bathroom breaks and has been able to relax his water intake as a result. They're both more relaxed. We purchase at our local grocery store (Hannaford here in NY) for about $1.31/lb. For the price, ingredients, and results - you can't beat it.
Example Output: 5

Example Input: great deal, especially for the price. Item arrived quicker than anticipated. This has saved me many trips to Dunkin Doniuts as well as saving me paying double the price for a cup of hot chocolate that's just as good. Looking for more to stockpile!
