Example Input: I have been searching for a natural lemonade drink mix that would actually taste good.  This is not one of them.  Did not like the the bitter taste of this drink mix. I can make my own fresh squeezed lemonade better than this stuff.  In the mean time I purchase Newmans Own ready made lemonade if I don't have the time to make my own lemonade.
Example Output: 2

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 these for pancakes, and I haven't used it to make any other recipes, so I cannot speak for how it makes biscuits, or any other item. But for pancakes, it's a no-go. They have a hint of pancake-flavor with lots of butter & syrup; but I don't like smoothering my pancakes in fattening syrup, so these pancakes are NOT for me. Moving on to other mixes...
