Example Input: really gets the mouth watering, a little over $3.00 at BIG5, the price listed here is insane!
Example Output: Positive

Example Input: Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money
Example Output: Negative

Example Input: I bought this based on a friend's recommendation, but was disappointed.  Although I checked the sizing chart, the item seemed too big and heavy for my dog. I recommend going one size down from what they recommend.  Also - although my dog loves playing with her stuff-a-ball toy, she will barely go near this thing. So - the one doesn't necessarily imply like for this item.  I suspect this would work best for a dog with strong food motivation. My doesn't like it at all.  As a toy, it's not much fun, unless a dog really wants food badly and is willing to put a lot of work into it.
Example Output:
Negative
