Input: Consider Input: Great selection of chips & very fresh. If you are are looking for a healthy alternative to fried potato chips & don't like the fake taste of baked, these are just the most amazing chips you can eat. I bought 2 cases & every time I'm at Target or our Super Box Store I make sure to pick them up!!

Output: Positive

Input: Consider Input: Please think twice about purchasing this product, especially if you have a small-breed dog. I was lured by the cute, gimmicky labeling and sold by the ingredient list, but I twice fed Merrick canned food to both of my dogs, and BOTH times, BOTH dogs were diagnosed with pancreatitis -- an illness which is dangerous, extremely painful to the animal, and which requires hospitalization. I'm not sure if the fat content in those particular cans was high, or if Merrick uses an ingredient/additive that somehow sickened both of my (unrelated) dogs, but this food made them very ill. After their second hospitalization for pancreatitis, I spoke with other folks who had stopped feeding Merrick to their small-breed dogs for the same reason -- the food caused vomiting, diarrhea, and lethargy in their pets.

Output: Negative

Input: Consider Input: Don't waste your money on these. These are practically flavorless, yet still feel a little greasy in your mouth. Yuck. If you're looking for some great onion-flavored snacks, just buy the Alexia Onion Strips. They're light years ahead of these. Seriously.
Output: Negative
