Example Input: I used the small cup setting and even opened up the cap and scraped the excess mix out of the cup and it is still very weak tasting.
Example Output: 2

Example Input: I bought 21 0z freeze dried liver. Half the container was filled with powder instead of pieces/chunks. I feel I was betrayed by the company. Hence I did not get what I paid for
Example Output: 3

Example Input: My parents fell in love with 'San Francisco Bay Coffee Company' coffee, which use to be available at our local AZ Costco. For christmas I looked every where for this coffee & found what I thought was a great value on Amazon. When I bought it (12/21/11) there was "No Image Available", should have been my first warning sign. They had lots of pictures of the 12oz bags of coffee from the San Francisco Bay Coffee Co, but I wanted something bigger, and this was 2 lbs. Now there is a picture availble, but if you look closely it's "Roger's Family Company" coffee, who is technically located near the San Francisco Bay Area. So if you're in love with San Francisco Bay Coffee Company, don't buy this coffee. But on the upside, since I waited till the last minute to buy it, I gave it to my parents for christmas anyway & explained what happened, but they said the coffee was pretty decent. So still makes a nice cup of coffee, just not San Francisco Bay Coffee Company coffee.
