Example Input: Although it sounded delicious, I was very disappointed in this coffee. The coffee has a strange, chemical aftertaste ... cup after cup, not just once.  Even when it brews, it creates a chemical sort of aroma.  In fact, because our single-serve pod coffee brewer was new, I started thinking the problem was the brewer.  We assumed it was a left-over manufacturing plastic or metal aftertaste coming through in the water.  I even e-mailed the coffee machine maker (Bunn) to see how to remove the aftertaste.  Imagine our surprise when a month later we opened a new pack of pods (regular Colombian, not flavored) and were delighted that our machine makes great coffee.  When we made a cup of the Senseo Vanilla again -- back came the off-taste and aroma.  Perhaps it's the "artificial flavors" used?  Be forewarned!
Example Output: Negative

Example Input: I love this tea. And it makes you feel very healthy, which is so needed during the Christmas and New Year season.. I haven't used it in one week, and I can soooo feel my body needing a good detox.  I recommend for anyone who has stomach issues, over indulges, and wants to feel generally better.
Example Output: Positive

Example Input: The product says a twist because of carbonation. Well after pouring the drink over 3 pieces of ice the carbonation was gone.  The carbonation is definitely light and does not last.  As far as the taste goes I did not care for the taste at all. It left a bad after taste in my mouth I cannot recommend this product. I will stick with regular juice at a much lower cost.  To be fair I gave it two stars because my wife thought it was OK.
Example Output:
Negative
