Example Input: I have been making Belgian waffles using the Stonewall Kitchen Farmhouse Pancake and Waffle Mix for over three years. My waffles are undoubtedly the best ever!!! I like my waffles light and crisp - I can't stand a heavy soggy waffle. These just melt in your mouth. I have made homemade waffles, but I have yet to find anything that can compare to this mix.
Example Output: 5

Example Input: I gave this product a one because zero wasn't an option. This is like a can of generic tomato soup with some overcooked bits of fish scraps in it. The only lobster in the soup was some shell. It was salty, fishy, nasty and inedible. Not only that, but 11 of the 12 cans were dented. A complete waste of money. Beyond disappointing. It made me angry.
