Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.
Example Output: 5

Example Input: I ordered these to make s'mores. I liked the ingredient list, no HFCS. However, they come more like a box of Wheat Thins. They are not large enough for s'mores, and many of them are broken upon arrival. They do taste good though, as a sweet snack.
Example Output: 3

Example Input: I bought this strawberry extract hoping to spruce up a strawberry wine that ended up with less flavor than I'd original expected. (A common problem in some fruit wines.)  This is, indeed, good strawberry flavor!  Just add to your sugary concoction (be it a baking good, a dessert or a drink) to either give strawberry flavor (or add to existing flavor), and presto, just about everyone will be licking their lips (and maybe fingers).  For those interested, I found the right addition to a liquid volume to be 4 oz of extract per 1 gallon of liquid.
Example Output:
