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.

Ex Output:
Positive


Ex Input:
Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?

Ex Output:
Negative


Ex Input:
I have two boxers, male and female. After about 30 minutes of the expected use, the male grabbed the end of the rope, shook and shattered the plastic threaded bottom right off the bottle against the corner of a door frame.  Concept is intriguing for the dogs but the plastic is too brittle. They didn't have the toy long enough to get to chewing on the rubber ball at the end.

Ex Output:

Negative
