Example Input: I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!
Example Output: 5

Example Input: Not quiet what I was expecting.  The cherries were dried and could not taste the brandy.  The dark chocolate was good but too crunchy.
Example Output: 3

Example Input: I drink this tea plain (without sugar or milk), and it has a pleasant aroma.  The price from Amazon is cheaper than my local grocery store.  One reviewer is right, I think it has some herbal smell to make up the aroma.  So the label "Imperial Blend" kind of implied the herb.  I am not exactly a black tea drinker, so this tea is a surprise, and affordable too.  I usually prefer White Chinese tea, like White Peony, but it is more expensive, and requires lower temperature water.  But this is black tea, and this aroma kind of remind me the 'softness' of white tea.
