Example Input: I drank this coffee over 30 years ago when I lived in The Netherlands. So glad that I can get it through Amazon. Strong, full bodied but easy on the tummy!!!
Example Output: 5

Example Input: In all fairness my friend absolutely loves this product. I purchased it based upon his suggestion. Unfortunately, the smell (oil I am assuming) of it cooking made me feel ill. Even though the product cooked perfectly, the smell lingered in my microwave for well over a day.
Example Output: 2

Example Input: This product is BEYOND AMAZING! I have been cooking pancakes in assorted ways for four decades. And, for home use, no other product comes close to this Bisquick Gluten Free Mix. It is superior not only to every gluten-free product on the matter; it is ALSO superior to every other mix (gluten-free or not) on the market. Friends and family are constantly amazed and surprised when I serve them breakfast. So, to everyone and anyone, don't make the mistake of associating this Bisquick product w/ other gluten-free products that result in food that tastes like cardboard. Last thought: Thanks to Amazon for making it available as a subscription purchase, since I can no longer find it in any South Florida supermarkets.
