Input: Consider Input: I am training for a half marathon.  At the start of my training I wasn't taking cherry juice.  As I increased my long runs each week my knees and hips were so sore.  I started to take this cherry concentrate and ever since then I have felt pretty good.  I take the juice every morning with my breakfast.  It has a very strong flavor but mixes well with apple or orange juice.  The half marathon I'm running in is this weekend and I feel ready for it thanks in part to the cherry juice helping reduce the pain.  This stuff works for me.

Output: Positive


Input: Consider Input: I bought these chips looking at its sale rank as one of the most sold chips on amazon.com. Unfortunately, I was highly disappointed. Way too much vinegar and they aren't like regular potato chips, some weird "pops".

Output: Negative


Input: Consider Input: I have two small dogs who have [[ASIN:B00139ZPKM Newman's Own #0174;Organics Advanced Dog Chicken & Rice Formula, 12.5 Pound Bag]]  Their only treats were Cheerios.  When I switched to Newman's Own brand, I was pleasantly surprised to notice they stopped their occasional vomiting.  With all the trouble caused by lack of standards in the industry, I immediately thought "if I can't trust Paul Newman's foods, whose can I trust".  And, they love it.


Output: Positive
