Example Input: I love this product! It is the best natural sweetener I have ever tried, and I have tried many. You can use also as pancake syrup or as a substitute for honey on your peanut butter and honey sandwich. It last a long time, and is a good value.
Example Output: 5

Example Input: Short and sweet.....The product itself is top notch and my two GSD's love it. However, the last shipment looked like it was packaged by a three year old and thus it arrived via UPS with a can lid popped open spilling its contents over the other dented cans. Another case arrived seperately which was properly packaged using air pillows and was fine. Don't get sloppy Amazon. It will cost you customers.
Example Output: 3

Example Input: The taste is great but most of the crackers are broken.  I am maybe getting 12 whole crackers per box.  The first time I ordered these there were several broken but this time there are more broken than whole.
Example Output:
3
