Example Input: We'll see how these work out in our family over time. I'm not sure that I am disciplined enough to make good use of them, although it might be a good technique for teaching my dog. They appear to be good for what they are, a very tiny, but healthy, reward. Right now I can visualize them being used as a reward for following commands, a training tool. I was surprised at how tiny these treats were. They seem to taste good enough, but they are miniscule! They are just a fraction longer than a small paperclip and about half as wide, maybe 1/4 as thick.  My dog was a little annoyed, but took it when I gave it to him. That was yesterday. Today he came in excited to get his "treat", looked at it as if to say, "You've GOT to be KIDDING!" Then he took it and ate it. A little later I offered him another one. He put it on the floor and looked hopefully at his stash of larger treats, but when he didn't get one, he went back and took this one.  I think these might be good for rewards for obeying commands. Treats? That's stretching it.  They may also be good for my son's dog who rarely gets treats because she's overweight and would eat the whole entire refrigerator full of food if allowed. At least she would get a treat. Large treats take her 5 seconds. She'll probably inhale these, one second max.  I like the fact that these are low-fat, with no added salt, no refined sugar, no artificial flavors, colors or preservatives. It says, "Treats Baked With Natural Peanut Butter." 
 Polarity: Positive
Example Output: True

Example Input: I thought this sounded like the perfect solution for taking nutritious wholesome food with us for our 8 month old baby on our vacation out of the country where I am worried we won't have very many fruit and vegetable options.  I have been making my own baby food with organic ingredients for the last 2 months.  I was excited to get the package today and ripped open the sweet potatoes, one of my daughter's homemade favorites.  I was extremely disgusted by the smell of the powder but decided to put some water in and give it a try anyway (hoping that the hydration would somehow help the mixture).  I tried a bite and these don't even taste anything like sweet potatoes.  They are very dark brown and tasted like minerals and quite unnatural.  My daughter ate the two bites I gave her but I felt too guilty feeding her anymore and dumped out the bowl...and my garbage smells terrible now. 
 Polarity: Positive
Example Output: False

Example Input: I have tried a lot of S&V chips and these are the best!  Real sea salt and REAL vinegar!  Mouth-watering flavor & crispiness.  Not for the faint of heart - the flavor is very authentic!  :)

True
