You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example 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.
Example Output: Positive

Example Input: A while ago I got a bag of the BBQ at a store to go with my lunch and I loved these so when I was searching amazon and found these on subscribe and save I knew that this was something that I had to have for my lunches. I love the fact you get all the different flavors and as of yet I have not found a flavor I did not like. Being from England I am very picky about my flavors of chips or crisps as I would call them as there seems to be such limited flavors but this box gives me flavors I can't complain. I also love the fact that 5% fat is the fat content which just makes them an even better snack. My only issue now is that I have to fight my husband and son over them because they love them just as much as I do. I have now had to go to a box a month but even then I am not sure I can have enough for the month with the three of us eating them every chance we can.
Example Output: Positive

Example Input: I was really rooting for this toy to work out, because my Frenchie Tobias loves playing with plastic bottles and he loves treats. The Tug a jug should be the perfect combo, right? The one I purchased had the rope, not the rubber thing. In theory, when you tip the toy treats should fall out relatively easily, according to various instructions and videos I found through internet searches. But even with small kibble, it is extremely difficult to get any treats out of the toy. Poor Tobias was quite frustrated. I helped him out by holding onto the bottle so that he could tug on the rope. He pulled quite hard for a good five minutes, after which one piece of kibble fell out.  He's actually quite clever, and he's extremely food motivated. I don't know if something was wrong with this particular Tug a jug, that it was so difficult to get the treats out, but it's definitely not working out.  I only give two stars because he did not destroy it, although he was throwing it around and chomping on the bottle part. He did leave scratches all over it, but hasn't yet managed to crack it. However, I think it's only a matter of time.
